The Twilight star shed his clothes and donned a pair of tightie-whities in a campaign remniscent of the one that made Marky-Mark a star back in the 90s for Calvin's latest underwear collection called X.

Kellan may have lost out on the role of Conan, but if this is his consolation prize, we're glad he didn't win!

Also featured in the new campaign are hot True Blood star Mechad Brooks, Spanish tennis star Fernando Verdasco and Japanese athlete Hidetoshi Nakata.


But ladies, you won't just have to salivate over these guys in 2-D, according to Marie Claire, the masterminds at Calvin Klein have created an interactive campaign, with interviews and behind-the-scenes video from the shoot, as well as a 3-D version of the advertisements!

Shirtless Kellan in 3-D? Yes, please!
