Kellan Lutz Goes Shirtless-Sexy For Calvin Klein

Calvin Klein knows where to put his new underwear.

Calvin Klein promises that his new line of underwear for men will undergo the company's most digital campaign ever...and based on Kellan Lutz's, uh, enthusiasm to participate, clearly it's one of the sexiest as well.

Who wouldn't love seeing what Kellan has going on underneath his clothes?! Chief creative officer for Calvin Klein underwear Bob Mizzoli said the concept behind this campaign was "bold, graphic and provocative, as always." They've also corraled True Blood's Mehcad Brooks, Spanish tennis star Fernando Verdasco and Japanese athlete Hidetoshi Nakata to model for the X line.

The X campaign launches on March 1, and sources say we can expect to see digital adverts and interviews with the four sexy models. (A wise move, as men in underwear on billboards are a traffic hazard for me.) Meanwhile, UsMagazine.com asked Kellan Lutz how he got into shape for the shots. Lutz answered, "I swear, candy helps! Gummy bears! It helps fight the hunger of higher calorie foods, but it is bad for the teeth."

We like sugar too, Kellan. A lot.

Meanwhile someone who's not consuming much sugar these days? Tiger Woods' wife Elin Nordegren. We have the scoop on what made her lose 10 lbs. since Tiger's sex scandal exploded -- get the story here. Plus, when you're done drooling over Kellan, we have more American fashion phenomena.
