Justin Timberlake is perhaps one of the most successful singers turned actors. Justin first hit the spot light as part of the best boy band ever, 'N SYNC, before heading off on his own successful solo career. Despite all of this it was his awesome role as a model in the Disney Channel original movie Model Behavior that started off his successful acting career. Since then Justin has starred in some intense fair like Alpha Dog and The Social Network, mixed with more ridiculous stuff like Bad Teacher and Friends With Benefits. Justin's currently got three more movies in production, so it doesn't look like he'll be heading back ot the music scene any time soon.
