"21 Jump Street" star Richard Grieco doesn't react well when the cuffs are getting slapped on him, as proven by this video of his DFW airport bust for public intoxication.

Police body cam footage, obtained by TMZ, shows Grieco angrily storming away from the American Airlines ticket counter in Dallas when a cop confronts him. Richard's pretty indignant at first, even asking the officer, "You guys know who I am?"

He then tried to talk his way out of his drunken situation, but it doesn't work. Cops put him under arrest and gave him a pop quiz on his level of inebriation. Watch ... you can't say he passed the test, but TBH -- it also seemed unnecessary to grill him.

It was obvious he was wasted. Richard slurred, sobbed and insisted he didn't do anything wrong as he was led away in handcuffs.

Things didn't get much better for the former TV police officer when he got to the station. He continued crying and claimed he was being singled out because he's famous.

Juice WRLD's death has raised serious issues ... were the feds targeting him because he's a rich, young, black rapper who flies in private jets? And, since Kanye and Joel Osteen are taking their show on the road, could Vegas be far behind? So, we gotta ask ...

Ohio State superstar Chase Young -- the projected #1 overall pick in the 2020 NFL Draft -- says he's not thinking about declaring for the draft and the "plan" is to return to school.

... But you know what they say about plans. They change.

TMZ Sports spoke with the Heisman finalist in NYC on Friday before Saturday's big ceremony ... and, despite the MASSIVE contract he could have come April, Young says that's not on his mind.

Young -- a 20-year-old junior -- has been a dominant, uncontrollable force on defense for the Buckeyes this season ... racking up 16.5 sacks (a school record) despite being suspended 2 games.

So, yeah, whoever sits at the top of the draft is gonna want to either take Young or his old teammate/LSU sensation Joe Burrow ... but it sounds like the Bucks could come out winners. Maybe.

We also talked to Young about the upcoming Fiesta Bowl matchup with Clemson ... and he sounds ready to go.

Jamie Foxx was in the mood to go, go, go to town on a bottle of tequila with Lil Jon ... because that's just how he does 52!!!

Jamie hit up Hakkasan Nightclub at MGM Grand in Las Vegas just after midnight Friday -- the official kickoff for his birthday -- and put his heart and soul into chugging the bottle ... with encouragement from Jon and the crowd.

We're told Foxx arrived with a group of about 20 people ready to party with him for his 52nd bday, and they got a VIP table next to the DJ booth ... where Lil Jon was performing.

Shots were flowing, of course, and both guys took pulls straight from the bottle to get things going. We're told LJ got Jamie onstage around 2:45 AM and told the house, "I’ve known Jamie for a long time, and he’s a good, real person. He ain’t down with all that Hollywood BS."

The duo then had some more Don Julio 1942 and danced to Lil Jon's classic track, "Turn Down For What" ... before he popped a bottle of champagne and showered Foxx.

Charles Oakley says even though the dude's a LEGEND in New York, Patrick Ewing simply ain't the right guy to take over for David Fizdale as Knicks head coach.

But, don't worry, Oak's got someone in mind -- Mark Jackson!!

TMZ Sports spoke with the ex-NY star about the coaching vacancy ... and, while he lists off a number of ex-Knicks who are qualified for the gig, Ewing ain't one of them.

Why??

"Ya gotta be a different type of coach than Patrick," Oak tells us. "I think he tried before and they didn’t hire him. So, I don’t know. We’ll see what happens."

Also, why??

The guy Kevin Hart believes tried to extort him in the sex tape scandal ... is 2 more steps closer to getting off scot-free in the case after a new court order.

According to docs, obtained by TMZ, J.T. Jackson scored in court Friday when the judge dropped 2 of the 3 remaining charges he was facing. The judge said there was insufficient evidence to move forward with prosecuting Kevin's ex-friend with attempted concealing and selling stolen property, and one count of unauthorized use of personal identifying information -- basically, identity theft.

Jackson is still facing an additional count of identity theft, a felony ... in connection with the sex tape. Prosecutors alleged Jackson tried to score money from Kevin in exchange for the 2017 video of Kevin with Montia Sabbag in a Las Vegas hotel room.

Remember, the stiffest charge Jackson was facing -- attempted extortion -- was dropped back in September. As we reported, prosecutors didn't think that charge would stick because Jackson never directly made a specific financial demand of Kevin or his people.

Jackson's attorney, Jacob Glucksman, tells us, "We’ve maintained innocence since day one and as things have unfolded our beliefs have been confirmed. We will continue to fight this until Mr. Jackson’s name is cleared.

He adds, "The D.A. is grasping at straws and is being pressured by Mr. Hart's team of lawyers and agents, but we will continue to prevail."

Janoris Jenkins says he now understands how hurtful the r-word can be -- telling TMZ Sports he won't use the term again and vows to learn from this experience.

Just hours after the NY Giants released Jenkins for using the word to insult a critic on Twitter, the NFL star agreed to speak with TMZ's Evan Rosenblum, a parent of a 4-year-old special needs daughter.

During the conversation, Evan explained why using the r-word as an insult is particularly hurtful for special needs families -- and Jenkins called it a "learning moment."

"It's always a learning moment, man. Everybody's going to learn from different situations ... move forward and learn."

Five Finger Death Punch's Jason Hook is currently recovering after multiple emergency room visits finally revealed he desperately needed to have his gallbladder removed.

A rep for the heavy metal band tells TMZ ... Jason had been experiencing pain that prompted 2 visits to the emergency room. But, the pain persisted ... and finally, during a third ER visit, doctors determined Jason needed to have his gallbladder removed due to blockage.

We're told Jason went under the knife Thursday night and just hours after the band was forced to postpone a show in Duluth, Minnesota. The band, naturally, was there at the hospital to support Jason.

Seems Jason's gonna recover just fine ... and fans who missed out on the show should not fret. The rep tells us 5FDP will be rescheduling affected shows.

The band's currently near the end of its U.S. tour leg. Just 2 other gigs remain -- at CHI Health Center in Omaha, Nebraska on Saturday and Wells Fargo Arena in Des Moines, Iowa on Sunday.

Boxing legend Leon Spinks is battling prostate cancer that spread to his bladder -- but the family is hopeful he'll pull through.

TMZ Sports broke the story ... 66-year-old Spinks has been fighting for his life in a Las Vegas hospital.

Now, a family spokesperson is revealing more details about Leon's condition.

"Leon is currently in intensive care of a Las Vegas hospital receiving attentive medical care to suppress prostate cancer which he was diagnosed with earlier this year and has since spread to his bladder."

"The last few months have been an agonizing roller coaster for Leon and his wife, Brenda, with continuous hospital stays."

"Leon is showing small signs of improvement and progress. A miraculous fighter his entire life, we are optimistic and hopeful that he will  move out of ICU soon."

"The power of prayer is real and his family is beyond grateful for all of the tremendous love and support."

Eva Marcille is taking round one in the child custody battle her ex-BF started, now that a judge in Georgia's told him to kick rocks ... back to Cali.

According to new legal docs obtained by TMZ ... the 'Real Housewives of Atlanta' star will maintain full custody of her and Kevin McCall's 5-year-old daughter, Marley Rae. The reason's simple ... Kevin failed to show why the case belonged in Georgia when an L.A. Superior Court judge issued the original custody order.

As we first reported, Eva and Kevin have been going at it in court for some time now. She begged the judge NOT to give him custody ... claiming he's a violent "ticking time bomb."

Last month, Kevin went to court to plead his case but that went south too. He got into a tussle with a cop in court, and took a nasty tumble down an escalator. Kevin believes he was the victim in that incident.

And, it gets worse for Kevin ... according to legal docs, there's a warrant out for his arrest in L.A. for missing a court date in his felony domestic violence case involving another woman.

Juice WRLD's closest relatives and friends are paying their final respects to the late rapper at his funeral in Illinois.

Juice WRLD -- born Jarad Anthony Higgins -- had an open-casket funeral Friday at Holy Temple Cathedral Church of God in Christ in Harvey, Illinois ... about 45 minutes south of the rapper's hometown of Chicago.

The program included a collage of pictures featuring Juice WRLD. His mother, Carmella Wallace, also paid tribute to her son. His siblings and grandmother also shared some words.

Several staffers and execs from Interscope -- his record label -- attended, as did Juice's friend and fellow rapper, Ski Mask the Slump God.

'Mad Men' star Christina Hendricks has filed for divorce from her husband, Geoffrey Arend,  after 10 years of marriage.

Hendricks filed docs in L.A. Friday, a few months after announcing the couple was going their separate ways. The two got hitched in 2009 and did not have any children together.

Back in October, the couple said, "12 years ago we fell in love and became partners. We joined our two amazing families, had countless laughs, made wonderful friends and were blessed with incredible opportunities."

They continued, "Today we take our next step together, but on separate paths. We will always be grateful for the love we’ve shared and will always work together to raise our two beautiful dogs."

Christina played Joan Holloway on "Mad Men" from 2007-2015. She also voiced the character of Gabby Gabby in "Toy Story 4." Arend is an actor as well, starring in ABC's "Body of Proof" and was in "Madam Secretary" for 5 seasons.

Christina and Geoffrey were introduced by Christina's former "Mad Men" costar Vincent Kartheiser. This was the first marriage for both Christina and Arend.

Jane Fonda's ever-growing celebrity crew of climate change activists has a new recruit -- Sally Field ... and she's been arrested for the cause too.

The legendary actress was hauled away by Capitol police in D.C. Friday for protesting on the steps of the building ... just like Fonda, several more members of Hollywood's elite and many other concerned citizens the past 10 weeks of Jane's "Fire Drill Friday" initiative.

Sally spoke to the crowd before her arrest, addressing this week's theme of transitioning to a green future ... and cited her Oscar-winning film, "Norma Rae," for inspiration in getting it done.

It's unclear how many people were arrested on a rainy Friday along with Field, but once again it seems like Fonda ducked trouble.

As we've reported ... Jane's been cautiously avoiding getting locked up after 4 previous arrests for protesting, because a 5th could lead to substantial jail time and her 'FDF' folks want her around for her leadership.

That hasn't stopped other stars from joining the arrest club, though ... Paul Sheer, Diane Lane, Piper Perabo, Amber Valletta, Sam Waterston, Ted Danson, Rosanna Arquette and Catherine Keener have all taken one for the team since the movement began.
