Bringing in a 1920s big band flair to the 2013 Grammy stage Sunday night, Justin Timberlake made a comeback and did it big.

Performing music from his forthcoming album, 'The 20/20 Experience,' the crooner sang 'Suit and Tie' and also debuted a new track.

Showing his support for JT, Jay-Z walked into the performance from stage right for his part on 'Suit & Tie' -- this was probably one of the smoothest entrances that's been done on the Grammys in some time.

Timberlake also debuted a new song from 'The 20/20 Experience' called 'Pusher Girl Love, which is a smooth R&B track that could possibly be the LP's second single.

JT proved that he's never lost his swagger -- if anything, it just grew -- enough for Beyonce, who introduced him alongside Ellen Degeneres, giving him props and calling him "an artist who is a true triple threat."
