Whether you’re trying to lose or gain weight, there’s no time like the present to get started.

Even though he hasn’t been officially attached to The Three Stooges project, Jim Carrey has already begun his personal preparations. According to his girlfriend, Jenny McCarthy, that means extra helpings of dessert.

To play the role of Curly Howard, the Yes Man star hopes to pack an extra 50 pounds to his frame. Jenny told Ellen Degeneres on the daytime talk show that audiences will eventually be “blown away” by his overall transformation. That includes his impersonation of the famous character.

“I have no idea what it’s going to be like when he hits near 300 pounds. But, you know, he’s in his comedy. He works hard at it,” McCarthy stated.

So far Senn Penn has already been confirmed for the Farrelly brothers comedy. (He’ll play screen legend Larry Fine.) Meanwhile, another Oscar winner, Benicio Del Toro (Che) is being courted for the role of Moe Howard.
