We're used to seeing celebs balloon and shrink to suit a movie role. Now Russell Crowe is the latest star to beef up -- the Aussie actor recently gained an astounding 63 lbs to star alongside Leonardo DiCaprio in Body of Lies, earning him a barrage of headlines proclaiming, 'From Hunk to Chunk!'

"I'll have the cheeseburger for breakfast, thank you," Crowe admitted in a recent interview talking about his weight gain. He also indulged in more than a few cupcakes. One diet no-no he didn't rely on to the pack on the pounds? Alcohol. "The drinking thing has sort of taken a different place in my life since I had kids. There's a whole lot of things I don't do anymore because it affects my level of patience. I don't want to be in that place where I'm exasperated with these beautiful children.

Too bad losing the weight is so difficult -- having cheeseburgers for breakfast sounds kind of fun, don't you think?
