Returning with his latest album, 24K Magic, Bruno Mars has been doing the promo circuit. So it was no surprise that he joined James Corden on his ever so popular "Carpool Karaoke."

The duo sang tracks like "Uptown Funk," "Locked Out of Heaven" and the latest, "24K Magic." While those were great renditions, it was the dance-worthy "Perm," that stole the show since James wore the same outfit Bruno had on.

The guys also tried on random hats, chatted about undressing their lady loves and Bruno's early Elvis impersonation days.
