HOT PHOTOS: Kellan Lutz for Calvin Klein underwear revealed

Though Taylor Lautner's sculpted body was a major component in marketing "The Twilight Saga: New Moon," his vampire costar Kellan Lutz gives him a run for his money today with the release of Lutz's Calvin Klein underwear ad.

Lutz, 24, is one of four men chosen to represent Calvin Klein X -- a new range of briefs that will be marketed globally in the same campaign, encouraging their customers to "mark your spot."

Lutz is joined by "True Blood's" Mehcad Brooks, soccer star Hidetoshi Nakata and 26-year-old tennis pro Fernando Verdasco in the just-released stills. The guys were shot by fashion photog Mikael Jansson in New York.

Starting Feb. 15, you'll also see the men in action with video and digital components on a microsite devoted entirely to the undies (check out XMarkYourSpot.com after Valentine's Day).

In a few short months, Lutz will hit to road with his fellow Cullens, such as Robert Pattinson, Peter Facinelli, Ashley Greene and their on-screen human cohort Kristen Stewart, to promote "The Twilight Saga: Eclipse."
