Cleveland Cavaliers

LeBron James turned all the way up at the Cleveland Cavs practice on Wednesday -- dancing hard in the gym with Kyrie Irving and Iman Shumpert ... and it's kinda awesome.

While most of the guys were working out in the team practice facility, Bron took a break when Playboi Carti's hit song, "Magnolia" came over the speakers.

The beat took hold. The guys danced it out. Bron's got moves.

Of course, the guys are in great spirits and well rested and ran through the Toronto Raptors in 4 games. Now, it's a waiting game to see who they get in the next round.

Why not turn up?!

Khloe Kardashian's safety is clearly a high priority at Quicken Loans Arena -- because there was a personal security detail assigned to her on Wednesday when the Cavs played the Raptors.

The reality star was in the crowd to support her boyfriend, Tristan Thompson -- but when it came time to leave, she had an arena security officer escorting her out -- and another officer keeping fans at bay.

We're told when nature called, a female security officer even escorted Khloe into the VIP restroom.

Khloe is becoming a fan favorite in Cleveland -- one witness tells us she took a bunch of pics with fans ... you can see her stop to pose with one very excited lady in our video.

Plus, she's also becoming friends with Cleveland Browns star Joe Haden and his wife. They not only socialized during the game, Khloe (along with her sisters, Kim and Kourtney) hit up a local amusement park with the Hadens the night before.

LeBron James is continuing to give back to his hometown in a HUGE way ... this time, he's opening his own public school for at-risk kids in Akron.

LBJ and his Family Foundation announced the plans to open the I Promise School ... with the goal to open its doors to 3rd and 4th graders in the Fall of 2018, and expand to 1st - 8th graders by 2022.

The project will focus on youth in similar situations the Cavs superstar experienced growing up.

"This school is so important to me because our vision is to create a place for the kids in Akron who need it most -- those that could fall through the cracks if we don't do something," LeBron says.

How do you rebound from blowing a 26 point lead in the 4th quarter? If you're LeBron James ... you hit the club!!

Bron -- along with J.R. Smith and Tristan Thompson -- hit up LIV nightclub in Miami hours after the Cavs lost to the Atlanta Hawks in ATL.

It was a shocking loss since the Cavs were up 26 points going into the 4th quarter. The game went into overtime where the Hawks put 'em away.

But after the final buzzer, the guys got on a jet and flew to Miami and partied with the likes of boxing star Adrien Broner.

The Cavs play the Miami Heat on Monday -- but LeBron will reportedly sit the game out to rest up.

The man being hailed as a HERO for breaking up a teen street fight in Atlantic City is crediting LeBron James for making the video go viral -- and now he's calling on the NBA star for more help.

Ibn Ali Miller hasn't just become an Internet sensation for talking sense into 2 brawling teenagers, he's also been honored by city officials.

Miller tells TMZ Sports it was LeBron who got the ball rolling by posting the video on his social media -- "If he doesn't give me a shout-out, none of this ever happens."

He even gives a personal message to Bron -- inviting him to the community so he can continue to help out with the youth.

By the way, Ibn was out shooting hoops with the neighborhood kids when we spoke with him ... and got love from a bunch of proud locals ... including cops and cons!

Big news for J.R. Smith and his family ... their micro-preemie baby Dakota is thiiiis close to crossing the 3-pound mark and her breathing tube is out!

Here's LeBron James putting his royal pipes to good use ... singing happy birthday to his All-Star point guard, Kyrie Irving, and the video is downright adorable.

Irving turned 25 today, and LeBron decided to mark the occasion with a few notes belted out on the team plane ... which he documented on social media for the world to see.

They beat the Bucks Monday night, but LeBron James, Kyrie Irving and J.R. Smith still had energy to put on a show AFTER the final buzzer ... with another round of dope handshakes.

The handshake game has been a thing for the Cavs for years ... and it keeps getting better.

Khloe Kardashian's got Tristan Thompson's back AND his front ... she's now rocking his favorite gear, and further proving she always pledges allegiance to her man.

The couple hit up a theme park while on vacay in Ocho Rios, Jamaica ... and as you can see, Khloe gives Nike prime real estate. She's also pimping the Swoosh with her kicks.

Tristan's peeps at Nike gotta love seeing this ... since Khloe's got a much wider audience than her NBA bf -- she's got more than 60 million followers on Instagram to his 1.3 mil. You gotta wonder if Tristan's agent will try to squeeze some dough out of Nike.

We've seen it before ... Khloe rocked Adidas when she was with James Harden.

Could an NBA team made up of the best former Kentucky players be able to beat the defending world champion Cleveland Cavaliers to win a ring?

"F*****' RIGHT!"

DeMarcus Cousins CLEARLY agrees with John Calipari ... who said this week that a team of Boogie, Karl-Anthony Towns, John Wall, Devin Booker and Anthony Davis would be able to win an NBA title.

Looks like Kevin Love is off to a great post-surgery recovery on his left knee ... because the Cleveland Cavs star was already walking around the streets of NYC last night and TMZ Sports has the video.

Love underwent arthroscopic surgery on Tuesday in NYC where a doctor removed loose bodies from the knee. He's expected to be out around 6 weeks.

But Wednesday night, he was already moving pretty well on his way out of a Ralph Lauren fashion show with his girlfriend, Kate Bock.

It's great news for Cavs fans and Polo fans ... 'cause the collection looked dope!

Who's got the balls to talk trash to LeBron James???? (besides Charles Barkley) ... how about the GREATEST competitor in the history of "The Challenge!!!"

TMZ Sports spoke with 'Challenge' legend Johnny Bananas ... who's DOMINATED on the MTV show for years ... and he strongly believes LeBron wouldn't stand a chance in his world.

FYI, "The Challenge" is a bunch of hot dudes and chicks who party their faces off and sometimes bang each other at night ... and then go to war in grueling physical competitions during the day. New season premieres tonight.

It's crazy ... these people are legit athletes.

So, we asked Johnny how a world-class physical specimen like LeBron would hold up. He ain't too confident in the King.

J.R. Smith's miracle continues ... the NBA star finally got to hold his preemie daughter (born after only 21 weeks) ... and says it's one of the greatest days of his life.

As we previously reported, Smith's wife gave birth to baby Dakota in early January almost 5 months before her due date. Dakota only weighed 1 pound at birth.

Now, more than a month later ... Dakota is still fighting and doctors determined she's strong enough to allow her parents to hold her in the NICU.

Smith posted a photo of their first "skin to skin" session. Smith wrote, "Today is one of the greatest days of my life. Today I get to hold my youngest for the first time! GOD is GREAT! #DakotaStrong."

J.R.'s entire family has been by Dakota's side at the hospital -- even reading to her as she continues to battle.

LeBron James WENT OFF on Charles Barkley last night ... blasting the NBA legend as a "hater" with a violent, sketchy and downright shameful past.

James was speaking with ESPN after the Cavs lost to the Mavs on Monday and was asked about Barkley's recent criticism of his leadership.

"He's a hater," LeBron said ... "What makes what he says credible? Because he's on TV?"

Then he REALLY went in.

"I'm not going to let him disrespect my legacy like that," James said.

"I'm not the one who threw somebody through a window. I never spit on a kid. I never had unpaid debt in Las Vegas. I never said, 'I'm not a role model.' I never showed up to All-Star Weekend on Sunday because I was in Vegas all weekend partying."

"All I've done for my entire career is represent the NBA the right way. Fourteen years, never got in trouble. Respected the game. Print that."

LeBron James just took a shot at Donald Trump.

The NBA superstar was talking to the media about the NBA All-Star rosters and was asked his thought about some players turning in "goofy" ballots as a joke.

His response ... "There's always goofy votes. Donald Trump is our president."

LeBron James has previously said he's undecided about going to a Trump White House if the Cavs win the NBA title ... saying, "We’ll have to cross that road, I guess. We’ll see. I would love to have to cross that road."

LeBron James ate like true king with prime meats on the menu to celebrate his 32nd birthday.

The Chosen One hit up Fahrenheit Friday night -- the night of his birthday -- in Charlotte with a bunch of his teammates ... including Kyrie Irving, Kevin Love and Tristan Thompson.

We're told he rolled in around 8:30 PM and the group sat in a private room ... where they ordered $3k worth of food and drinks. LeBron specially requested a blackened salmon salad while the rest of the ballers feasted on 60-day aged NY steaks and lobster tails.

They washed it down with some Hennessy and Moscow Mules before the big dessert -- chocolate and vanilla bean cake ... delivered by Chef Rocco Whalen himself.

So, why Charlotte? The Cavs play the Hornets tonight.
