Mario Lopez cheats on women, and it’s up to us ladies to watch out for each other when we get involved with dudes who enjoy double dipping behind their girlfriends’ backs. So let this be a universal warning! Don’t date this douche. Mario’s ex-wife Ali Landry dumped him after two weeks of marriage because he “cheated on her for several years,” and recently his romance with dance partner Karina Smirnoff ended after it was revealed that he had been nailing a Hooters girl secretly for a year. A year! Karina got a little misty eyed when discussing the break up on Chelsea Handler‘s show (see above), and we don’t blame her. Nothing hurts more than being scammed by some asshole with nice dimples. So pay attention, next girlfriend of Mario Lopez! We know it must be fun dating A.C. Slater, but ‘faithful’ is not in his vocabulary.
