Summer/Beach

One of the perks of being a pro athlete ... you look DAMN GOOD in a bikini!

Just ask Lindsey Vonn, Mackenzie Dern, Sydney Leroux, Maria Sharapova and WNBA rookie Lexie Brown-- world class jocks who couldn't wait to show off their physiques when Spring sprung!

We couldn't help but notice some of the biggest female stars in sports are showing off on the Gram -- so, we pulled some of our faves for one amazing gallery.

Paulina Gretzky, Bre Tiesi, Arianny Celeste and Adrienne Bosh ... yeah, they're here too.

Travis Barker doesn't think there should be an age limit for rocking out, so he's throwing what could possibly be the most kid-friendly music festival ever, complete with a breastfeeding area for new moms.

Barker's Back to the Beach Fest is going down next weekend in Huntington State Beach in Southern California. Headliners include 311, Sublime With Rome, as well as the original Fishbone lineup, Barker playing with Goldfinger and loads more.

Kids under 10 get in free, which isn't unusual for music festivals, but BTTB doesn't want to exclude anyone, so they're setting up a special quiet zone for nursing moms.

That's not all ... there will also be a Lil Punk Zone where kids can rock out safely. We're told Barker got the inspiration from taking his own kids on the road everywhere and wanted other families to see what it's like to rock out with their little ones. All those diapers should also keep the porta potty lines down, too.

What's better than Patriots offseason workouts?

If you're Rob Gronkowski, the answer is a pool day with your smokin' hot model girlfriend!!

FYI, things have been heating up between the Patriots star and his lady friend, Camille Kostek -- an ex-Patriots cheerleader who SLAYED the Sports Illustrated swimsuit mag earlier this year.

On Tuesday, Gronk and his GF hit up Camille's grammy's house somewhere that's not Boston ... and the Pro Bowl tight end went full Optimus Prime, transforming into her HUMAN WATER SKI!

Yeah ... Camille likey.

The hot-bod couple also got in some canoodling with a cute-as-hell puppy belonging to Gronk's little bro, Glenn -- and we're starting to get the feeling this is a lot more than a spring fling.

Amy Roloff knows how to do vacation the right way -- dance your ass off as much as possible ... and enter a cannonball contest.

The matriarch of "Little People, Big World" didn't let her stature stop her from grabbing the spotlight Wednesday on a cruise ship in the Caribbean. Amy was shaking her booty and having a blast before she took the plunge in the competition.

We're told the top finishers got prizes sent to their rooms, and based on the size of Amy's splash, it's no surprise she didn't win ... but she did come in third!

It's unclear what prize she got, but the reality show mom def won some respect for going for it.

Von Miller clearly isn't fazed by an investigation into whether he illegally caught a hammerhead shark in Miami, 'cause he continues to party it up there ... in open waters.

The star Broncos linebacker was spotted in the Sunshine State again this weekend enjoying himself on a yacht with a ton of girls and a few pals in tow -- including 49ers rookie Adrian Colbert. Von even hopped on a jet ski with a chick at one point for a quick spin.

As you can see from the photos, Von doesn't seem to be the slightest bit concerned over the Florida Fish and Wildlife Conservation Commission looking into whether he broke any laws a couple weeks ago in capturing and then releasing a wild hammerhead shark.

PETA flipped their lid over video and photos of the incident, claiming the crew had illegally caught and killed the animal. They ran their complaint all the way up the flagpole in Florida ... which is now officially under investigation.

Von Miller's fishing expedition in Florida has ignited an investigation after PETA accused the NFL star of illegally catching a hammerhead shark ... TMZ Sports has learned.

Miller and some friends went fishing in Miami last week and reeled in the 9-and-a-half foot shark -- which they later threw back in the ocean.

PETA -- People for the Ethical Treatment of Animals -- went berserk over the footage ... accusing Von's group of illegally catching and killing the animal.

PETA vowed to follow up with wildlife officials and said they would "ensure Miller is held accountable."

The complaint got all the way to the Florida Fish and Wildlife Conservation Commission -- a government law enforcement agency that regulates hunting and fishing.

We spoke with FWC Public Information Coordinator Rob Klepper who tells us, "FWC has received the images and video and is looking into whether or not a violation occurred in this incident."

Unclear what the punishment would be if officials found Miller broke any laws -- we're looking into it.

Story developing ...

Chris Hemsworth got ALL UP in his wife's business when he got a handful of her ass during a family day at the beach.

No doubt about it ... Chris was a huge fan of Elsa Pataky's choice in swimwear -- a very small black bikini -- during their family's Sunday funday. The stupidly hot couple's been married for more than 7 years now, so they obviously made it through that 7-year-itch thing, just fine.

The Hemsworths were hosting Matt Damon and his family in their hometown of Byron Bay, Australia this weekend. They all went to a music festival together, but we're guessing Chris and Elsa had a much better time at the beach.

Matt Damon made the mistake of sitting next to Chris Hemsworth in public, and Mother Nature made him pay for it -- well, a large bird with full bowels actually made him pay.

Check out Matt's shirt -- front and back -- 'cause he got bombed by some bird down in Byron Bay, Australia. Matt spent Sunday hanging with Chris and his fam at the beach -- y'know they're locals in the Bay.

Matt seemed slightly amused after the s**tstorm, and attempted to clean up. He also changed his hat ... just in case.

Far as we can tell, Thor emerged totally unscathed, still ridiculously hot ... and without sleeves.

Before Larsa Pippen went egg huntin' with the kiddies on Sunday, she hit the sunny shores of South Beach to brighten up everyone's Easter weekend.

And yes, there was plenty of cake to go around.

No sign of Scottie or the kids ... but seems like Larsa was enjoying her solo outing.

The 40-something mother of 4 frolicked in the sand rockin' an itty bitty bikini ... looking absolutely incredible, as she usually does.

Here's more proof that Von Miller is the NFL's Steve Irwin ... landing a HUGE hammerhead shark after a wild tussle with the beast of the deep!

It all went down off the shores of Miami Beach ... where the Denver Broncos star and his bros set sail on a sport fishing trip, 'cause why the hell not?

The crew caught a bunch of cool fishies ... but none could compare to their 9-AND-A-HALF-FOOT shark which, according to the boat captain, was the biggest hammerhead he's seen all season.

FYI, the guys made sure to throw it back in the water after bro'in out on their find.

Remember -- this is a dude that wrastled a live gator just a couple months back ... and we got a feeling he's only gonna keep upping the ante.

Calvin Harris can't shake it off ... his ex, that is. And you really can't blame him.

The superstar DJ hit up Cabo San Lucas with his on-off -- and apparently now totally on again -- ex-gf Aarika Wolf. She's the incredibly gorgeous bikini model Calvin dated for nearly a year back in 2015 ... before he left her for Taylor Swift.

And we know how that ended ... but we digress.

G-Eazy and Halsey, as a couple, are grabbing a lot of attention -- but he's just grabbing her ass.

The rapper and singer were spotted relaxing Monday in Miami, just a couple days after grinding all over each other during a performance at E11Even nightclub. They left little to the imagination here ... especially Halsey in her white bikini.

The "Him & I" duo weren't there alone -- a bunch of friends also joined them on a yacht, but G still wasn't shy about getting handsy with his girl.

Danielle Knudson did an oceanside photo shoot for H&M -- but we're not sure what the hell she's advertising ... besides her half-naked body all covered in sand.

The Canadian model hit up a beach in Tulum, Mexico Wednesday for a shoot with the beleaguered Swedish retail company, where she started off in a 2-piece bikini, and ended up topless ... layered with sand ... and on top of some very lucky dude.

We imagine they were showing off some of H&M's swim line -- but it's anyone's guess with how much skin is showing here. At least it ain't "monkey in the jungle" Winter wear again.

Rebecca Gayheart's in full revenge bod mode, hitting a Mexican beach on the heels of her divorce from Eric Dane.

Rebecca threw on a bikini and soaked up el sol Monday in Playa del Carmen -- and it's crystal clear she's living her best life in the coastal resort town. Looks like she was hanging with a friend who understands the fine art of chillaxing through a crisis.

TMZ broke the story ... Rebecca filed for divorce from former "Grey's Anatomy" star Eric just 2 days after Valentine's, and after 14 years of marriage. Eric and the former '90210' star have 2 daughters, ages 6 and 7.

She's asking for spousal support as well as joint legal and physical custody.

Johnny Manziel and his smokin' hot wife, Bre Tiesi, aren't wasting any time celebrating the ol' ball and chain ... whisking away to Cabo for some married fun in the sun!!

TMZ Sports broke the story ... Johnny and Bre got hitched in a private California ceremony last week -- 1 year after Manziel popped the question.

Word is they might have a proper wedding bash for all the homies later this year ... but first, they're hitting the sweet Mexican sand for their 1st vacay as Mr. and Mrs. Manziel!

As for what they're up to ... it's all pretty cute-sy stuff -- taste-testing some salsa, lounging by the water, even trolling each other on their March Madness allegiances (seems Bre ain't a Texas A&M fan).

Congrats!!

Bre Tiesi's killing 2 birds with one stone -- hitting the beach to show off her expensive new wedding ring ... and flaunt her bangin' bod once again.

Johnny Manziel's wife soaked up the sun in Miami Wednesday afternoon in a tiny bikini ... which has kind of become her thing. Johnny was nowhere to be seen, so it's possible he's back to practicing for a hopeful return to the NFL.

TMZ Sports broke the story ... Johnny and Bre tied the knot last week in a private ceremony in California. The couple got engaged last March.
