An early progenitor of "creepy-sexy," Jared Leto looks just about as sleazy as a former teen heartthrob can get, yet there's still something about him that the girls love. His personal style is classic Sex Addicts Anonymous, and that's why we think he's a plausible "keeping track of his conquests" candidate. Also, could the members of his band 30 Seconds to Mars serve as his dude pack? All too easily.
