"Remember Wilmer Valderrama? Didn't think so," relationship expert Matt Titus says of the "That 70s Show" star. "That's because he's not dating another celeb at the moment. He really knew how to use that to his advantage and sort of become an 'It Boy' for a moment." Lindsay Lohan and Ashley Simpson famously feuded over Valderrama, who also dated Mandy Moore. Simpson reportedly penned her hit "Boyfriend" about the incident. And Lohan has said about her player ex: "There'd be all these girls around, and he'd flirt with them, and I couldn't handle it."
