The first trailer for "The Hangover Part 3" has hit the web.  This one features the guys heading back to Vegas for more insanity.  It opens May 24th

JUSTIN BIEBER COLLAPSED during his concert in London last night.  With a few songs left to go, he felt lightheaded and went backstage.  Supposedly, he fainted . . . and needed to be treated with oxygen.  Eventually, he came back out, did four more songs, and went to the hospital.  Don't worry though, it sounds like he's OK.  I’m not sure why he’s obsessed with showing of his skinny body now- but he posted a shirtless picture of himself lying in the hospital bed. 

JOY BEHAR is leaving "The View" after its current season, which will make BARBARA WALTERS the last remaining original yenta . . . unless she leaves, too.  Joy says it just "seemed like the right time [to go]."  She adds that she'd like to get back to doing stand-up, and potentially launch another talk show of her own.

Earlier this week, MILEY CYRUS denied that she'd called off her wedding to LIAM HEMSWORTH.  But last night she was spotted out in Los Angeles . . . MINUS HER ENGAGEMENT RING.

DEMI MOORE filed a response to ASHTON KUTCHER'S divorce papers, and she wants SPOUSAL SUPPORT.  She's also asking that Ashton pay her legal fees.  According to TMZ, Demi has WAY more money than Ashton.  Although Ashton did make $24 million last year alone, thanks to "Two and a Half Men".  Since Demi is already set for life, it's not likely a judge will award her any support. 

KELLY OSBOURNE suffered a seizure in front of a live studio audience while taping her show "Fashion Police" yesterday.  Witnesses say Kelly turned to guest host MELISSA RIVERS and said, quote, "I don't feel good" . . . then fell out of her chair to the floor and started shaking.  Melissa went down to the floor to help her . . . and an audience member who happened to be some kind of emergency responder jumped in as well.  Fellow host JOAN RIVERS later said Kelly is "fine". 

CHRIS BROWN was caught on video blowing up at the valet parking guy at a bowling alley over a TEN DOLLAR CHARGE.  Chris got right in the guy's face and told him, quote, "Gimme my [effing] keys!  [Eff] ten dollars!"  He added, quote, "We gonna turn this whole spot up . . . I promise you."  Luckily, one of Chris' boys paid the money, so Chris didn't have to "turn the whole spot up."
