Trying to take after Marky Mark’s Calvin Klein ads of the 90’s is proving to be a tough feat for Kellan Lutz. How’s he doing?

Kellan was recently unveiled as the new “it” boy for CK tighty whities and is showing off his abs in their new “X” campaign. Alongside Mehcad Brooks, Fernando Verdasco and Hidetoshi Nakata, Kellan is showing off the goodies.

The new campaign is reportedly going to be the most digital to date. It’s set to launch on March 1st with plans to release behind-the-scenes videos along with interviews of the four hot guys that were chosen for the campaign.

As far as how Kellan got in shape for the famous shoot, he said, “I swear, candy helps! Gummy bears! It helps fight the hunger of higher calorie foods, but it is bad for the teeth.”
