"I've been sworn to secrecy by Steven Spielberg and George Lucas not to tell you the title of the next 'Indiana Jones' movie," said the actor, who is in the film's cast. "What the hell! I'm 21 and we're in Vegas, baby, so here it goes. This is the first time it's ever been heard. The official title for the next 'Indiana Jones' installment is 'Indiana Jones and the Kingdom of the Crystal Skull.' It's a big deal. Nobody has ever heard it before."

The last time Harrison Ford played the adventurer was in "Indiana Jones and the Last Crusade" in 1989. The new film is due in theaters in 2008.

LaBeouf also announced the winner of the VMA for "Female Artist of the Year" -- Fergie. However, she was not at the event to accept the prize.

She beat out fellow nominees Beyonce, Rihanna, Nelly Furtado and Amy Winehouse.
