If I were Victoria Beckham, I would be holding on to David's ass for dear life too!  Here's a charming picture of America's most famous immigrants as they enter their big "Welcome to LA" bash thrown by Tom Cruise, Katie Holmes, Will Smith and his wife Jada.

Everyone who was anyone was at the big bash including Ron Howard, Matthew Perry, Brooke Shields, Jon Voight, Tyrese Gibson, Stevie Wonder, Serena Williams, Lil' Kim, Forest Whitaker... the list goes on and on.

Our invitation must have gotten lost in the mail.
