Kellan Lutz Appears in CK Undie Ad

Unlike his underage cocktease co-star Taylor Lautner, Twilight star Kellan Lutz is 23 and therefore, exempt for child porn legalities. We've kept our eyes on his bulge and nutsack before, but now he's appeared in a Calvin Klein underwear ad showing a lot more of his beautiful bod. Calvin Klein also released this sexy behind-the-scenes vid in which he shares his diet and workout secrets! Bikini season is just around the corner, boys!
