UPDATE:
Colin Farrell is good guess, and, sure, I can see some Rollins in there, too, and definitely the CSI guy (George Eads)--he'd crossed my mind, too. (My original, and very lame guess, was Nick Lachey.) But I think Sean Kleefled nailed it: Dominic Purcell from Prison Break. The likeness is even clearer in the pictures of bald Nick earlier in the same issue.
