With his chiseled abs, perfectly manscaped hair, and bright white smile, you'd think Mario Lopez was one of the most squeaky clean men in the business. (He's not! Ali Landry annulled her marriage to the actor after two weeks amidst rumors he cheated with multiple women.) We're guessing it's the hair gel, spray tan, and smile-whitening bleach that make this actor-host one of the cheesiest dudes in Hollywood. (Mexican Fabio, anyone?) The "Extra" host is almost obsessive about his good looks, so we imagine he likes his cheese in the cottage form -- because it's low in fat.
