2 Chainz gave a swagged-out performance on 'Late Night with Jimmy Fallon.'

The rapper wore black-and-white leather pants, shades and at least two chains for his television rendition of 'Feds Watching.' Instead of singing to pre-recorded tunes, Chainz was backed up by The Roots. And while Pharrell is on the track, Deuce's DJ filled in from time to time in the producer's absence.

The entire studio audience were up out of their seats jamming to the beat.

Jimmy Fallon made mention of the rhymer's new album, 'B.O.A.T.S II: Me Time,' due in stores Sept 10.
