Justin Bieber "What Do You Mean?" (ft. the Roots) (live on 'Fallon')
Disgraced pre-teen pop hunk Justin Bieber seems poised for a comeback thanks to his smooth new Skrillex-produced single "What Do You Mean?"
 
He's already shared a steamy clip for the song, but last night (September 2), he dropped by The Tonight Show Starring Jimmy Fallon to deliver a rather impressive live rendition of the track.
 
Backed by the always on-point Roots — including an added rap verse courtesy of Black Thought — the Biebs wormed his way into television sets and back into hearts across the world. Watch the performance below.
