OMG! Kellan Lutz Stripping Down to His Calvins

Muscled Twilight hunk will follow in Mark Wahlberg's footsteps as new spokesface and body for famed skivvies

Get ready for up close and personal shots of Kellan Lutz in nothing but his skivvies.

Sources confirm that the Twilight hunkster, 24, is the new face and bulge body of Calvin Klein underwear.

All those involved are staying tight-lipped about the new campaign, but I'm told we'll be seeing something early next year...

Calvin executives apparently want to model the ads after the famous Mark Wahlberg campaign in the '90s that was shot by the late, great celebrity photographer Herb Ritts, reports Fox411. Other celebs who have shown off their goods for CK include Antonio Sabato Jr. and Djimon Hounsou. Their female counterparts have included Eva Mendes and Hilary Swank.

This wouldn't be Lutz's first time at the modeling rodeo. He also posed and looked pretty for Abercrombie & Fitch.

And we all know how he doesn't mind if we stare look at his muscles. We're certainly not complaining, but it seems like every day we get another pic of Mr. Lutz walking around outside in a body-hugging tank top.

"I go to the gym maybe once or twice a week for 45 minutes," he told us earlier this year. "I hate running. I eat whatever I want. I eat pizza all the time. I have a candy drawer."
