You Might Want to Rethink

Kendall Jenner is painfully white, and we're not talking skin tone.

Check her out doing what looks at first like the Monster Mash Friday at Coachella. The moves changed, but not necessarily for the better.

Kendall was there with some chick friends ... no trace of Justin Bieber.

9:45 AM PT -- Big Sean just weighed in again, and tells TMZ ... someone, other than Bieber, pulled a fast one on him.

Justin Bieber got a little handsy with Ariana Grande during a performance Wednesday night ... much to the dismay of her boyfriend Big Sean, who went on Twitter and threatened him.

Bieber made a surprise appearance at Grande's concert at the Forum in L.A. Wednesday, where the two performed "As Long As You Love Me." Toward the end of the song, Justin calls her over, tells her to stand in front of him ... and throws his arms around her.

It's pretty apparent ... Ariana's not having it and she quickly disentangles.

But apparently not quick enough for Big Sean, who was in Canada -- and caught wind of Bieber's antics through social media. He tweeted (and later deleted), "This kid is about to learn not to touch my girl like that. Beliebe that."

Russell Crowe got prank called by Michael Jackson so often ... he can now do a pretty good impression -- and he uncorked it for our us in D.C.

Russell was heading into the premiere of his new flick, "The Water Diviner," and our photog, Colin, asked about his recent revelation that MJ busted his balls for 3 years with harassing fake calls -- think, "Is Seymour Butts there? How about Hugh Jass?"

Crowe tells us they'd actually shoot the breeze after the prank, and he was obviously listening closely to Michael. Watch the clip ... pretty funny to see Maximus using an MJ voice.

Ex-Florida State cornerback P.J. Williams -- a projected 1st round NFL Draft pick -- has plead NOT GUILTY to DUI ... though he admits he had been drinking earlier in the evening.

As we previously reported, Williams --who's 21-years-old -- was arrested while leaving a McDonald's parking lot in Tallahassee early Friday morning after hanging out at a local nightclub.

However, P.J.'s lawyer Jonathan Simon tells TMZ Sports the NFL prospect was the designated driver that night ... and had cut himself off HOURS before he got behind the wheel.

"He did have a drink or two earlier," Simon says ... "But at 3 AM, he was taking everyone to McDonald's. It's what 21-year-olds do."

Simon says Williams is adamant he was not driving drunk -- and plans to fight the case all the way to the end.

We're told Williams did NOT submit to a breathalyzer or a blood test during the arrest -- and Simon believes dash cam video of the incident could actually help P.J.'s case.

The case is due back in court soon.

Kylie Jenner pulled a Julianne Hough by posting pics of herself which appear to show her in black face ... and people are pissed.

Kylie originally posted the pics Saturday night, saying, "What I wish I looked like all the time."

She got backlash from folks who felt she crossed the line with black face, so Kylie deleted the pics, re-uploaded them and wrote, "This is a black light and neon lights. People lets all calm down."

Her response is not particularly responsive, so we gotta ask ...

The Indiana pizza guy who refused to cater gay weddings has made more in the last week than he probably made in years ... his supporters have almost made him a millionaire.

Kevin O'Connor has closed shop because of numerous threats, after he drew the line on gay marriage pizza celebrations.

O'Connor supporters started a GoFundMe account where people could give money to support O'Connor's family. The goal was to raise $25K.

As of Saturday morning ... they've hit $842,592. Nearly 30,000 people have donated money.

Cody Simpson is a robot ... or he's the biggest friggin' Knicks fan in the world, because not even a stone cold 10 like Gigi Hadid could break his steely gaze from the game.

Cody lived every dude's dream Wednesday night at Madison Square Garden ... courtside seats and a supermodel pawing at you like you're her first meal in weeks. Yet, all the Aussie singer cared about was watching the hapless Knicks lose to the Nets.

Memories Pizza -- the first Indiana business to declare it would refuse LGBT business -- got blasted on the Internet and by phone, but the owner says there's been a huge misunderstanding ... sorta.

Kevin O’Connor tells TMZ he's had to temporarily close his business after he told a reporter he would refuse to cater a gay wedding under Indiana's new Religious Freedom Restoration Act. O'Connor says he was immediately flooded by threatening phone calls, and social media postings.

O'Connor wants to clear up one thing: He says he would never deny service to gay people in his restaurant. However, due to his religious beliefs, he does not believe in gay marriage ... and that's why he wouldn't service one.

Meanwhile, he says the threats have been serious enough that he's closing his pizza joint ... at least until the dust settles.

Farrah Abraham is an example to young women on what NOT to do -- and yet pre-teen girls are flocking to her like she's a modern day Mother Teresa. Apologies to Mother Teresa's spirit.

Abraham and her sparkling resume -- teen mom, stripper, porn star, author, DUI arrestee -- were leaving Planet Hollywood in NYC ... when an alarmingly young fan stopped her for a photo.

And then we got an even bigger shock as Farrah revealed she's going to become a plastic surgeon! Seriously ... she says.

The phrase, "Do what you know" comes to mind ...

David Lee Roth has no one to blame but himself for that bloody gash he had on his nose during "Jimmy Kimmel Live!" ... because he whacked himself during his signature mic stand trick.

Roth and the rest of Van Halen reunited for an epic performance on "Kimmel" Monday night, but the sanitized version that aired didn't tell the whole story.

During the initial performance of "Panama" ... Roth hit himself in the face with his mic stand while twirling it, leaving a cut across the bridge of his nose.

He kept going, eventually walking offstage to grab a towel. He then patched it up with a band-aid and did the song again. That's the version that aired.

The show must go on.

Tara Reid accompanied a total stranger to a Hollywood tattoo parlor so he could get her name tattooed on his arm, but luckily for Tara ... she wasn't drunk enough to return the favor.

Reid and this guy (good luck trying to understand him when he slurs his name) met on a flight back from Ultra in Miami, and clearly they both enjoyed a few cocktails along the way.

We figured out the guy is DJ Crichy Crich -- and for some reason he and Tara thought it was a good idea to go straight from the airport to the tattoo parlor.

Unlike hangovers, that tat is pretty permanent.

With a devastating hit that would make J.J. Watt jealous, one of Riff Raff's bodyguards absolutely destroyed a fan who made the mistake of jumping onstage and trying to touch the rapper.

It happens real fast … the overzealous fan jumps onstage and simply taps Riff Raff twice on the shoulder before turning to walk away. But by then, it was too late … and Riff Raff's HUGE bodyguard comes flying out of nowhere and levels the guy.

As if that wasn't enough, the bodyguard then tosses the guy's limp body back into the crowd as if it were nothing.

You're not enjoying an Action Bronson concert ... until Action Bronson whips your ass and chucks you off the stage -- just ask the guy who got Bronson'd in NYC Tuesday night.

Bronson was doing a record release show at Terminal 5 when the hyped up fan jumped onstage and patiently waited for Action's wrath -- which he got.

Funny thing is ... you can tell from the video the guy LOVED it, and maybe even self-propelled himself off the stage. It's actually become a thing at Action's concerts -- fans crowd surf to the stage, so he can give 'em the ole heave-ho.

Justin Bieber's bodyguard has been in a heated standoff with photogs and cops ... but he's just been given a tough new detail ... babying Bieb's 8 oz. puppy.

Biebs isn't playing around when it comes to Esther -- the same adorable little Silky Terrier he wined and dined at Mastro's in Bev Hills on Sunday ... it looks like he's put his top dog, Michael Arana, on the job.

The good news ... if Arana can handle himself against a gaggle of Miami cops or some unruly London paps like he did in 2013, he can more than handle picking up Esther's doodie.

No shame in taking care of the lil' doggie, as long as he's not getting paid in kibble.

"Teen Mom 3" star Mackenzie McKee blames her no-good husband and diabetes for the crash that almost totaled her SUV ... but mostly her husband.

The MTV star told us on TMZ Live ... she was looking for Josh when she drove her Kia Sorento into a ditch.

She told us what Josh was doing in the Oklahoma boonies ... turns out he's just wild about hogs.

Vine star Cameron Dallas spent a lot more than six seconds in jail ... after he allegedly painted his apartment and everyone inside of it.

Law enforcement sources tell TMZ ... cops were called to Dallas' Hollywood pad Wednesday afternoon after neighbors complained about loud partying. When cops arrived, all was quiet and no one answered the door ... so they left.

Fast forward to 6 PM ... cops were called again after someone hurled a paint can out Dallas' sixth floor window, nearly hitting a woman below.

Cops arrived and discovered the entire apartment, along with everyone inside it, spattered with paint. Someone also hurled hue in the hallway.

Dallas was arrested on felony vandalism and held on $20,000 bail. He was released at 1:30 AM.

It appears the entire stunt was for a video. A few hours after his release, Dallas tweeted, "(: lets just say this video will be awesome..."

Dallas is known for throwing stuff off his balcony.
