Bruno Mars brought the funk to “Carpool Karaoke” when he hopped in the passenger seat with James Corden.

Mars sang “24K Magic” with the “Late Late Show” host, who teased the blinged-out singer for wearing an abundance of silk.

“If I was wearing that level of silk I think I would be happy as well,” he told Mars. “If I wore that, I’d look like I’m having a breakdown.”
