Biz Markie, Just a Friend

Biz Markie is best known for his tongue-in-cheek '80s songs "Just a Friend" and "Vapors," but these days he makes his living as a DJ who entertains with a mix of rock and rap — and often a performance of at least one of those hits. Producer and rapper David Banner is rumored to be playing Biz in Vapors, an upcoming movie about hip-hop's legendary Juice Crew, and Biz himself recently joined a handful of old-school heroes in embracing VH1's "celebreality" circuit, appearing on the weight-loss show Celebrity Fit Club.
