Justin Timberlake guest starred on Saturday Night Live and it was amazing! The Three Amigos guest starred for a funny 5-timers Club cold-open, including Chevy Chase, Steve Martin and Martin Short, Tom Hanks, Alec Baldwin and Dan Akroyd. Justin Timberlake reprised his singing advertisement character for a bring-it-on-down-to Veganville with a little Harlem Shake action and he performed tracks off his new 20/20 Experience album.
