Matt Damon is already generating Oscar-buzz for his role as a CIA informant in The Informant. The point of this story is he gained 30 pounds to play it. Now Jim Carrey's jumping on the fatty bandwagon, saying he can outweigh Damon for his upcoming role in the Three Stooges movie - and he's already started to heft it up.

The comedian has promised to gain 40-50 pounds for his role as Curly in "The Three Stooges" -- more than the 30 Matt put on for "The Informant!" -- and he showed off a chubbier figure on Thursday night at UCLA's 2009 Visionary Ball in Beverly Hills.

Weight wasn't the only thing Jim's added to his look -- he wore glasses and had grown a full beard.

Partner Jenny McCarthy, who stood by Jim's side on Thursday, previously told Access Hollywood's Billy Bush that she was looking forward to "dating Curly."

"He said, 'You know, I'm going to have to gain 40-50 pounds for this role.' And I said, 'Oh my God! I get to be dating Curly!' That is the greatest thing ever," she told Billy in April. (Access Hollywood)

Jenny McCartney's expectations for "the greatest thing ever," are clearly very low - but of course, we already knew that after she watched The Cable Guy and still decided to date Jim Carrey.
