Above, from People (January 14, 2013): Justin Theroux, 41, is lookin' pretty fine on his vacay with Jennifer Aniston. The phrase "business up front, party in the back" refers to a mullet, but here is applied to his (in this case) silly-looking tattoo. But it still makes me think of anal sex.

This may be Kellan Lutz's best candid ever, flashing his undies and his mischievous tongue during a shoot in Malibu, from Star (October 1, 2012). Bradley Cooper doesn't look half bad himself while promoting his movie Silver Linings Playbook, as seen in People (October 1, 2012):

Justin Theroux, about to be seen in Wanderlust with Jennifer Aniston, flashes some pubes and addresses the relationship in New York (February 20—27, 2012):

"I understand the curiosity, but other than saying I am happy, I am not going to indulge it. That's building your own torture device."

So is agreeing to star in Wanderlust. Yeesh, it's painfully unfunny. At least he—and especially co-star Paul Rudd—is adorable.
