Giannis Antetokounmpo is moving on from that crushing Conference Finals loss to the Raptors by getting right back in the gym ... and dancing his ass off!!

The Greek Freak and his fellow NBA playing brother, Kostas, channeled their inner MadeinTYO for their workout cooldowns ... bustin' out the woah dance while "Chucky Cheese" blasts in the background.

If you have no idea what these kids are trying to accomplish, check out this vid.

Giannis is obviously one of the best players on the planet right now ... but that doesn't make him immune to the IG trolls ... with some people joking his moves look like a grandpa trying to be cool.

Worth noting -- if you think these guys are good hoopers, the Antetokounmpos have a younger brother, Alex ... and Giannis previously told us he's gonna be the best in the bunch!!

3:40 PM PT -- Jay Glazer ran into Pratt at the gym and congratulated him, and Chris used it as an excuse to show off his wedding ring as well. Pratt also had a very quick but interesting message ... check it out.

2:26 PM PT -- Chris also seems to be in the mood to work out before he and his new bride get into honeymoon mode -- but he's doing so across town from his wife. The actor was spotted Tuesday leaving a WeHo gym, right around the time Kat was doing the same in Brentwood.

Sure, they just got hitched three days ago -- but hey, it's 2019. Do your thing, babe! See ya at home.

Katherine Schwarzenegger's not off on a fabulous honeymoon yet ... but she's still rocking that newlywed smile and GIANT ring while working on her fitness.

Katherine was beaming Tuesday as she left a pilates sesh in Brentwood. We're guessing that ear-to-ear grin has more to do with her husband, Chris Pratt, than working up a sweat ... but ya never know. She IS Arnold's daughter!

As we reported ... the couple tied the knot over the weekend at the ritzy San Ysidro Ranch in Montecito. The event, as you can imagine, was a pretty star-studded affair. Heck, the wedding rehearsal alone was at Rob Lowe's crib!

This is Katherine's first marriage, and Chris' second. He was famously married to Anna Faris, who was so happy for him and Katherine, she volunteered -- jokingly, we think -- to marry them.

That wasn't necessary, as it turned out, and the wedding went off without a hitch.

Congrats ... to Katherine, we mean. Pilates is hard!

Arnold Schwarzenegger made a clean getaway when his bodyguard got into a showdown -- that involved a taser -- with an alleged bicycle thief outside of Gold's Gym.

The bizarre confrontation went down Friday in Venice, CA, just as Arnold was wrapping up his morning pump.

We're told he was inside the gym when a man with a bandana on his face came up on the rack outside and tried to steal Arnold's gold bike. The Governator had his own private security parked nearby in an SUV keeping an eye on things, and they sprung into action.

One of Arnold's guards busted the potential thief by pulling a Taser on his ass. While they stood a few feet apart, Schwarzenegger swooped in, grabbed his wheels and took off.

Justin Theroux's either throwing some serious muscle behind the #FreeBritney movement, OR he just likes super trendy tees that show off his muscles and his love for Britney Spears.

Justin was tooling around NYC Friday on his bicycle ... making sure his biceps and triceps got plenty of vitamin D while showing his love for early Brit.

His graphic tee -- sleeves optional -- featured the cover art for the 2001 "Britney" album. Justin definitely seems like a "Slave 4 U" kinda guy.

Based on how ripped the guns of Theroux were looking during his ride around Gotham, we'd say someone's gonna "Get it get it, get it get it" in the gym ... or wherever he's heading on his bike. He won't deny it, and he damn sure ain't trying to hide it!!!

Mandy Moore is getting some super cool social media content on her way up Mount Everest, but Sal Masekela says she's also putting herself in danger ... and she might not make it down alive!!!

We got the former X Games host at LAX Wednesday and asked him about the recent deaths at Mt. Everest ... and Sal delivers a dire warning to rich people who are climbing just for the social media snap -- and for Mandy, who just reached Everest's base camp.

This climbing season has already resulted in 11 deaths in the Himalayas, with the latest casualty an American lawyer. The way Sal sees it, even the most elite athletes can succumb to Everest's harsh conditions ... so Mandy's gotta be extra cautious, even though she's being guided by experts.

Kevin Hart says he's known around the gym as "The Rock" for his sculpted body ... and he's claiming Dwayne Johnson stole the famous handle and pawned it off as his own!!!

We got Kevin Monday in New York City and asked about getting in great shape for some recent movie roles, and that's when Kevin dropped a bombshell ... Dwayne's NOT the original 'Rock.'

Ya gotta see Kevin's reaction when our guy suggests the comedian needs a cool nickname like Dwayne's ... he's visually shocked and upset, imploring Dwayne he's got some 'splainin' to do!!!

We also wanted Kevin's take on Chris Rock crossing over to horror films and signing up to produce the next "Saw" chapter ... and gauged Kev's interest in getting involved with scary movies himself. Sounds like Kevin's got some demons to face before going down that road.

Kate Middleton designed a garden that she hopes will inspire others to get their kids outdoors and playing -- and her kids set a great example by leading the way on that front.

The Duke and Duchess of Cambridge had themselves quite a day exploring Kate's new "Back to Nature" garden that she's officially unveiling to the public in a few days as part of the annual Chelsea Flower Show. The point of all of it ... early childhood development and getting folks (especially kids) reacquainted with the great outdoors. A great cause, really.

Before she opened the doors to everyone else, she had Will bring their own kiddos by to scope the joint out. Prince George, Princess Charlotte and the newest addition, 1-year-old Prince Louis, definitely had their run of the place ... it's practically a kid's playland paradise.

Charlotte and Louis rode the rope swing, which looks super fun ... and Georgie boy dipped his toes in a running stream under a baby bridge. We don't usually say this ... but damn, this is cute.

Seeing how they got a little cousin now who'll be able to play along soon enough -- ya gotta imagine the Royals might be here quite a bit in the near future.

Britney Spears is getting back to that fit life on social media after checking out of a mental health facility, and she looks better than ever ... doing yoga in a two-piece.

The pop star posted a compilation video Sunday showing herself getting into a bunch of yoga poses outside while wearing a teeny bikini ... all set to Cardi B's "I Like It." Good song choice, 'cause Britney definitely comes with that energy with handstands, splits ... and pretty much everything in between.

It's been a little more than a week since she left the mental health facility she was staying at, and it looks like she's fully back into her routine. It also appears she's caught more of those UV rays she was somewhat lacking the last she was photographed in public.

As we told you ... Britney is still working through some unresolved issues regarding her medication, despite checking herself out of the facility she was at for 30 days.

We're told she'll continue receiving intensive therapy sessions while at home, but this vid's gotta be a good sign that things are getting back to normal.

Good for her.

If you're wondering what Megyn Kelly's been working on since her NBC exit -- these pics of her shredded body make it clear ... the woman's been working OUT!

The former NBC and FOX News host spent Easter weekend in the Bahamas. She did a lot of paddle boarding and let's just say her athletic talent is ABS-olutely showing. It's impressive, hard to argue there's something more impressive than her incredibly toned bod.

Check out the pics ... she wore the hell out of a very small bikini while flashing her $38 million smile throughout her vacay. Megyn, who hasn't been on the air since her NBC ouster last October, told us she'll be on TV again at some point this year.

Here's Rob Gronkowski showing he's still got a little football in him after retiring from the NFL -- throwing passes to fans in the Bahamas this weekend ... and showing off the scar from his back surgery.

Gronk and his swimsuit model girlfriend, Camille Kostek, spent Easter weekend right by the beach -- taking in some sun at a fancy resort in Nassau ... it's gorgeous.

Kostek shot footage of a shirtless Gronk playing catch with some kids -- and you can see the scar on his lower back from the procedure he underwent in Dec. 2016 to treat a herniated disc.

Gronk returned the following season and had a monster year -- he was named a 1st Team All-Pro in 2017. Pretty amazing comeback.

But now, it's a wrap for Gronk ... he officially announced his retirement from the NFL back in March and says he's excited for the next phase of his life.

Pauly D says Mike "The Situation" Sorrentino is holding up well behind bars ... and he's about to check up on the Sitch in person for a mini "Jersey Shore" reunion.

We got Pauly D heading into NBC Studios in NYC, and he gave us a super positive update on his buddy's prison stint. Sounds like Mike's making the most of his situation, all things considered.

Pauly D knows what's up, he says they communicate all the time -- and you can do the same, because Mike's an avid reader who loves getting fan mail.

Pauly says the best way for fans to show their support is by busting out a pen and paper and showing some love to Mike in prison.

Of course, there's nothing like a face-to-face meeting, and Pauly says his is going down soon.

Good news, bad news for Dave Bautista ...

Bad News ... someone lost control of their car Tuesday night and smashed through the front gate of Bautista's gym in Florida.

Good News ... miraculously, no one was hurt!!!

It all went down outside of Dave's boutique gym in Tampa -- which looks like a house from the front -- where a black SUV crashed into the outside fence of the property in the middle of the night.

Bautista personally went down to the gym to check out the damage -- and admits he was in a "sh*tty mood" when he saw what happened.

But, the former WWE superstar says, "Thankfully no one was hurt."

Several Tampa Police Dept. officers also responded to the crash scene -- and Bautista says they couldn't have been nicer and more understanding.

So, what did Bautista do next? He took pics with everyone!!!

10:36 AM PT -- Johnson finished the marathon in 3:09:07 ... JUST missing his 3-hour goal.

Still, an AMAZING performance from a guy running his very first 26.2 mile race.

His average time per mile was 7 minutes and 13 seconds. Incredible!

Congrats!!

Jimmie Johnson doesn't need a car to go fast -- the NASCAR driver is running the Boston Marathon and he's CRUSHING IT SO FAR ... on pace to finish right around the 3-hour mark!!

43-year-old Johnson's been training for months with the goal of breaking the 3-hour mark ... and at the time of this post, he's almost at the halfway point -- on pace for a 3:03 final time based on his splits.

What's even more amazing ... Jimmie's never completed a marathon before!

Oh, and on Saturday, he was RACING CARS -- he competed in the Toyota Owners 400, a 300-mile race at the Richmond Raceway in Virginia.

Jimmie is wearing bib #4848 during the marathon, a tribute to his #48 car.

Johnson says he's always wanted to run the marathon but his NASCAR schedule got in the way -- but this year, NASCAR shifted the schedule, which freed him up to run.

During his training, Johnson suffered injuries to his pelvis, left calf and IT band -- but battled through it ... and he's out there running right now!!

GO JIMMIE GO!!!

Lee Ann Yanni -- who suffered major injuries in the 2013 Boston Marathon Bombing -- is returning to course on Monday to run 26.2 miles ... all to raise money for military families in need.

Yanni was a spectator at the 2013 marathon when shrapnel from one of the bombs hit her leg causing broken bones, severed nerves and other major injuries.

But, Yanni is a beast -- and just 6 months later, she completed the Chicago Marathon in 5 hours, 43 minutes. Amazing!

She's since completed the Boston Marathon TWICE -- once in 2014 and again in 2015.

And, on Monday, she'll lace up her shoes to do it again -- not only to stick it to the scumbags behind the bombing but also to raise money for the Semper Fi Fund.

The Fund provides resources and support for combat-wounded, critically ill and catastrophically injured members of the U.S. Armed Forces and their families. It's a great cause.

So, where did Yanni find the physical and emotional strength to get back out there? We spoke with the 37-year-old who told us she couldn't have done it alone.

David Harbour gave "Hellboy" producers one hell of a scare ... he almost didn't fit into his demon superhero bodysuit because he was too jacked!!!

Harbour's trainer, Don Saladino, tells TMZ ... Harbour's 10-week workout regimen transformed him so much it set off a production panic. We're told producers were actually upset over the weight loss and body reshaping.

Check out the vid ... the celeb trainer, who also started his own "Hellboy" program, says it wasn't the case. He concedes, yes, Harbour's body drastically transformed ... but by packing on serious muscle. Nevertheless ... Saladino says he had to have a talk with his client about actually NOT being too strict on his diet. Must be nice.

No doubt Harbour -- proudly strutting a dad bod in "Stranger Things" as Sheriff Hopper -- looks like a badass in the movie, released Friday.

BTW ... most people who hire famous trainers usually request the Ryan Reynolds look. Not Harbour though!!! Now, about those abs ...

There will be no triumphant comeback for the Auburn gymnast who broke both of her legs during a floor routine at the NCAA Regional Semifinals ... Samantha Cerio says she's retiring from the sport.

Cerio snapped both of her legs while trying to land a handspring double front on Friday -- she was stretchered off the mat with 2 air casts.

**WARNING -- THE VIDEO IS GNARLY AND GRAPHIC**

Auburn went on to advance to the Regional Final ... but Cero says Friday was "my final night as a gymnast."

Cerio issued a statement saying, "After 18 years I am hanging up my grips and leaving the chalk behind."

The Auburn senior says she learned a lot from the sport -- including hard work, humility, integrity and dedication ... but has ultimately decided to move on.

"It may not have ended the way I had planned, but nothing ever goes as planned."

"Thank you Auburn family for giving me a home and a chance to continue doing the sport that will always be my first love. I am honored to have had the privilege to represent the navy and orange AU for the past 4 years with my team by my side. Thank you for letting me share my passion with you. Thank you for letting me be a part of something bigger than myself."
