Robin Thicke wasn't really dressed for it, but ... a bunch of high schoolers let him stand in for a photo anyway ... ON PROM NIGHT!

It went down last Saturday ... the 20 or so students from Eagle Rock High in northeast L.A. were waiting for a party bus to take them to prom when one recognized Alan Thicke's hunky pop-singer spawn shooting a music video across the street.

They called the "Blurred Lines" (No. 1 on iTunes this week!) singer over ... and he was more than happy to chill and take photos.

"He made our night!," said a student named Jesse. "When my other friends told me about their party buses, they really had nothing to say… I mean, we had Robin Thicke!”

The teens say Thicke asked if anyone wanted to appear in his video the following day ... we're told some of them took him up on it.

But probably just the goood giiiiiiiiiirls ...

NFL superstar LeSean McCoy has been sued by a woman who claims the running back humiliated her on a party bus -- sprayed her with a beverage -- and then booted her from the ride on the side of the Jersey Turnpike.

According to the lawsuit filed by a woman using the alias "Mary Roe" ... the Philadelphia Eagles RB had invited 15 women to join him on a party bus that went from Philly to a NYC nightclub on December 18, 2012.

During the trip, the lawsuit alleges, McCoy, along with his bodyguard and a couple of other guys, began to spray some of the women with water.

Roe claims she protested the water spraying ... so McCoy ordered his bodyguard Big John to "get her."

In the suit, filed May 10 in Philadelphia, the woman claims McCoy and/or Big John proceeded to hit her in the face, causing her to fall to the ground.

While she was on the floor, the men allegedly physically restrained her and poured a beverage onto her hair, clothes and body.

And if things couldn't get worse ... the woman claims McCoy and Big John then forcibly ejected her from the party bus on the side of the New Jersey Turnpike.

But some of the women allegedly complained to McCoy about Roe getting the boot -- so she was snatched back up from the side of the road and placed back on the bus.

The woman claims she was taken to a nearby rest stop -- where the football player once again ditched her -- and continued on with his party trip.

Roe is now suing for more than $50,000 in damages for assault and battery, intentional infliction of emotional distress, false imprisonment and negligence. Roe says she suffered head trauma, a disc protrusion on her spine, bad sprains, contusions and bruises all over her body, and severe shock.

We reached out to McCoy's reps -- and the Eagles -- so far, no word back.

 

Sayonara Stefon ... Bill Hader has announced he's leaving "Saturday Night Live" ... and this weekend's episode will be his last.

"It was a hard decision, but it has to happen at some point,” Hader told the New York Times ... adding, "It got to a point where I said, ‘Maybe it’s just time to go.'"

Hader has been with the show for the past 8 seasons.

The move is a big loss for the show -- which already lost Andy Samberg and Kristen Wiig last season. Seth Meyers is also set to leave next year, when he takes over "Late Night."

As for Stefon ... we'll miss ya pal.

Lil Wayne still hates the Miami Heat so much ... he hooked up the Chicago Bulls with free booze after they upset LeBron James and company -- and TMZ got a pic of their celebration.

It all went down Monday night at Excess Mondays at Mansion nightclub in Miami where, we're told, Wayne invited a few Bulls players (who were already in the club) to party with him ... just hours after they beat the Heat 93-86.

The guys with Weezy were (left to right) -- Mack Maine (pres. of Young Money Entertainment) ... along with Bulls' Taj Gibson, Richard Hamilton, Vladimir Radmanovic and Nazr Mohammed. 

Our sources say Wayne provided the boys with bottles of vodka and told 'em he was rooting for them to knock the Heat out of the playoffs.

Wayne's beef with the Heat started back in February -- when he claimed he was tossed out of a game in Miami for rooting for the Lakers.

The Bulls have lost to the Heat twice since this pic was taken ... so pretty soon they're gonna need a few bottles of vodka for a whole different reason.

Kerry Washington and Craig Robinson were spotted tearing up a dance floor -- and in the process reminding us that sometimes, just sometimes ... stereotypes can be awesome.

Everyone has a tequila story, and Khloe Kardashian and Kris Jenner had theirs Thursday night ... with an evening that started at a Mexican restaurant and ended with them getting KICKED OUT of Kim's house ... TMZ has learned. 

According to our sources, Khloe and Kris went out for a girls' night and hit up Casa Vega in the Valley for some dinner and a few margaritas (FORESHADOWING!!!!). The ladies had a good time and K&K even posted a pic of the pair wearing sombreros and captioned it "She's wild man" (see above).

We're told the pair took a car service and went straight from the restaurant to the popular West Hollywood bar The Abbey to shoot a scene for "Keeping Up With the Kardashians." The only problem ... they smartly decided they were too drunk to shoot ... so they left without even getting out of the SUV.

According to Abbey patrons, the ordeal pissed off management because they had roped off a prime section for the shoot.

But it doesn't end there ... Khloe and Kris then had the brilliant idea to go from the bar to Kim's house ... because who doesn't love partying with drunk women more than a PREGNANT CHICK?!?!?

It predictably didn't go well, and Kim told the girls to take a hike. 

And thus ends the story of the greatest episode of "KUWTK" that never was.

Things heated up last night at the "Peeples" premiere party in L.A. -- co-stars Craig Robinson and Kerry Washington busted out some INSANE moves on the dance floor ... and it was all caught on video.

The after-party went down at Lure nightclub in Hollywood -- and once Nelly's "Flap Your Wings" came on the loudspeaker ... 36-year-old Kerry unleashed some shockingly good moves.

Craig comes in about halfway through the video with the greatest opening maneuver ... so be patient.

And take notes.

"American Pie" party animal Tara Reid was 100% sober last night ... is what we would say if we didn't have this awesome video of her stumbling out of a Hollywood party. She has fun.

Check out TMZ on TV -- click here to see your local listings!

Tara Reid is most definitely nursing a Wednesday morning hangover right now ... 'cause she hit the clubs so hard last night, she could BARELY STAND on her way out.

It's your classic ... "girl walks into a bar, girl chugs a bunch of liquor inside of the bar, girl gets so plowed she needs help leaving the bar" story.

The good news -- Tara didn't get behind the wheel ... she had a driver take her home.

Smart.

Patrick Schwarzenegger used a FAKE ID to get into a Hollywood club this weekend ... and was only kicked out after he pelted the house DJ with ice cubes ... sources connected to the club tell TMZ.

We're told ... Arnold's kid -- who's only 19 years old -- used someone else's driver's license to get past the bouncers at The Sayers Club in L.A. on Saturday night ... and it worked.

But once he was inside, we're told Patrick was a total pain in the ass.

Sources tell us Patrick was rowdy and obnoxious ... and at one point, he began throwing ice cubes at the DJ. (His father did play Mr. Freeze, after all).

Once the ice began to fly, we're told club honchos recognized Patrick -- realized he was underage -- and kicked him out ASAP.

After he got the boot, TMZ shot footage of Patrick ranting about wanting to beat up the DJ.

Patrick wasn't arrested -- but using a fake ID is a misdemeanor in California, punishable by up to a year in jail and a $1,000 fine.

His father probably knew that already ... since, you know, he was the governor.

Multiple attempts to reach Patrick were unsuccessful.

Patrick Schwarzenegger won't be back ... to The Sayers Club ... 'cause Arnold's 19-year-old son was KICKED OUT of the nightclub on Saturday and threatened to "beat the f**k out of the DJ" ... and TMZ has the footage. 

Our cameras were rolling outside the club Saturday night ... when Patrick went on the rampage, bitching about the DJ to anyone who would listen.

"I'm gonna go beat the f**k out of the DJ," he told a group of friends while outside the club.

He then continued complaining to another friend, "Everyone around me wants to beat the f**k out of the DJ ... [it sounds like Patrick says 'gay boy'] ... I'll beat the f**k out of him."

"He kicks everybody out of his table, losing money for the club, losing money for the owner."

It's unclear WHY Patrick was kicked out of the club ... or even why he was allowed INSIDE the club in the first place, considering he's only 19.  

But as Patrick tries to get into an SUV to leave the scene, he's DENIED by the driver -- and Patrick proceeds to condescendingly wave his hand in the driver's face. Another diva moment.

You know who WASN'T kicked out of a nightclub Saturday night? Joseph Baena.


9:18 AM PT -- Patrick just tweeted "Excuse my language. I apologize" ... so he's addressed the swearing part, at least.
