Bieber And Corden Swag Out In Matching Tuxes And Turn Up The Funk In Post-Grammys 'Carpool Karaoke'

Nice tuxes.

After the 58th Grammy Awards concluded, Justin Bieber joined James Corden for a special "Carpool Karaoke" episode.

The duo, looking smashing in their matching white tuxedos, were on their way to Corden's taping of The Late Late Show.

During their drive through L.A., they decided to get a little turned up to Bruno Mars' and Marc Ronson's Grammy-winning Record of the Year, "Uptown Funk."

They also had some fun opening their Grammy goodie bags. Well, maybe the Biebs had a little more fun.

While the "Where Are Ü Now" singer got a dope Rolex, private plane tickets to the Maldives, and an iPad mini, James Corden got ... some chapstick and a map of Los Angeles.

Well, it's really the thought the counts, James.

Watch the episode below.
