The pre-Grammy bashes have already started, and last night partygoers at the Belvedere Red event at Avalon got more than just a performance by Usher -- they witnessed a bar brawl between Jamie Foxx and another patron!

Sources inside tell X17online that right before Usher took the stage, a man tried to hit Foxx, and the actor/singer threw back a punch to retaliate. Security guards broke up the fight, and Foxx was escorted to his car by a team of bodyguards after the show. Foxx was not hurt, and the police were not called, so it sounds like this is the last we're going to hear of this!

Charlie Sheen took a break from rehabbing at home yesterday to play some baseball at UCLA, but the Bruins baseball team didn't exactly give Sheen an invitation to crash their practice.

Marc Dellins, UCLA's Sports Information Director, tells X17online exclusively:

"Charlie was not invited to speak with the team. He was hitting with some current and former major leaguers prior to UCLA practice went over to the group of our players on his way off the field and spoke briefly to them."

The troubled Two and A Half Men star not only posed for photos with some professional ballplayers, but Sheen also took a moment to talk with the UCLA baseball team about the dangers of drugs.

In a brief statement, Sheen told the players:

"Stay off the crack. Drink chocolate milk. Enjoy your moment. That's all I've got."

UCLA's coach John Savage is helping Mr. Sheen get back in shape. As for Charlie's speech, let's hope he inspired a few of those college ball players to stay on the straight and narrow.

The moment we saw her step out of the car in that Basic Instinct-like dress, we knew this would happen.

When Lohan graced the LA Superior Court with her presence Wednesday, little did designer Kimberly Ovitz know her "Glavis Albino" minidress would gain the most incredible free press she could ever hope for.

After the world saw Lilo saunter into court wearing the curve-hugging ensemble, women everywhere were running to get their hands on the $575 now-infamous dress. But was Lohan given this dress as a gift to promote? Ovitz's rep said Lohan paid for it (unlike the necklace situation) in full, saying: "Kimberly had no role in Lindsay Lohan wearing the dress."

There's some good news and some bad news for you Lohan fans out there. Bloomingdale's, and Neiman Marcus, as well as online sellers Intermix and Shopbop, had already sold out of the dresses way before Lohan made the item a white-hot trend.

According to Ovitz's sales team, fewer than 1,000 dresses were made, but thanks to the troubled fashionista, the moment she stepped out in the dress phones were ringing off the hook with women begging for the frock. The designer immediately sent a message to retailers asking if they wanted a a second manufacturing and order of the dress, at $575 a pop.

An Ovitz sales associate told the New York Post:

"It's been a frenzy! We saw it [the Glavis Albino dress] on the cover The Post today. We know, definitely, that people want that dress again because of Lindsay."

Despite that little necklace slip up, La Lohan is still doing her part to boost the economy ... that's gotta count for something!

This is definitely the year for superhero films and fresh out of the gate is X-Men: First Class. The action flick, produced by Bryan Singer, is packed with out-of-this-world effects and a hot, new cast.

Jennifer Lawrence takes over for Rebecca Romijn as sexy Mystique while January Jones and James McAvoy add sizzle to the film's 1960's setting.

When asked about the pressure to come up with something new and exciting for the X-Men franchise, Bryan Singer said:

“You can never think about that. That’s just something you can torture yourself with or stress out about, but you can’t do that and sit there and think, ‘What are they doing? We need to do that.’ .... Your goal is to make a cool movie. You need to stay focused on that goal.”

X-Men: First Class hits theaters June 3.
