He probably got more people cursing than anyone else last year and it couldn't have made them happier. Cee Lo Green's contagious hit song "F--- You" for which he won a Grammy is one you're not likely to forget. Remember, though, it's not the first time Cee Lo's got us moving; as the voice of the duo Gnarls Barkley, he hit it big with 2006's "Crazy." Starting this spring, he'll be a coach on NBC's new reality series The Voice. Presumably the network will keep the bleeper button handy.
