Twilight's Kellan Lutz is the new face of Calvin Klein's male underwear collection, X. As we previously reported, Kellan will be making ads like Mark Wahlberg used to make 'em: shirtless, in black and white, and hawt!

The new Calvin Klein X ad campaign launches on March 1. Video interviews with Kellan Lutz and the other Calvin Klein models will appear in 3D.

So how did Kellan get in shape for the photo shoot? "I swear, candy helps! Gummy bears! It helps fight the hunger of higher calorie foods, but it is bad for the teeth."

Who knew candy could get you so ripped? Female celebrities love to deny dieting and exercising; it's about time a male celebrity did the same. Like the higher calorie foods Kellan was trying to avoid, his ad is tempting. Before he transitioned into acting, he used to be a model for Abercrombie & Fitch. Welcome back to modeling Kellan!
