No, it's not a young boy-bander like Harry Styles, who was spotted posing in a thong, or a veteran in the modeling industry like Twilight star Kellan Lutz.

At least Affleck isn't following Justin Bieber's fashion sense with his pants falling down. That might not be the best look for a father of three.
