What a sweet surprise!
Well, get this—the Twilight star isn't the only hot man in the ads!
True Blood's oh-my-god-look-at-his-abs star Mehcad Brooks, Spanish tennis star Fernando Verdasco and Japanese footballer Hidetoshi Nakata are also showing off their assets.
All four are in bulge- and booty-hugging briefs from Calvin's newest underwear collection, X. When the entire campaign launches March 1, we'll also be treated to 3-D images of the ads.
And there's more! Behind-the-scenes videos will give you a look inside the making of the ads.
So, after drooling over looking at Lutz and the others, who else would you like to see posing in nothing but their Calvins? Leave your comments below.
