WATCH: Bruno Mars on 'Carpool Karaoke'

MANILA, Philippines – Bruno Mars is James Corden's latest guest on "Carpool Karaoke!"

In the Wednesday, December 14 episode of The Late Late Show with James Corden, Bruno took the passenger seat of James' car and kept him company on his way to work.

The two partied to Bruno's hits like "24K Magic" and "Locked Out of Heaven," and tried on a few silly hats to test out James' theory that Bruno can wear anything and look good.

Before the Bruno Mars episode, James had Madonna in his passenger seat for "Carpool Karaoke." James has had many other artists and personalities on the segment too, like Michelle Obama, Selena Gomez, and Mariah Carey.
