Bruno Mars Brings the (Uptown) Funk to Carpool Karaoke — Grade It!

Bruno Mars brought the house down during James Corden’s most recent drive to work. Don’t believe us? Just watch.

The four-time Grammy winner joined the The Late Late Show host for Carpool Karaoke on Tuesday in support of his third studio album “24K Magic.” Over the course of their 15-minute drive, the virtuosic duo harmonized on some of Mars’ greatest hits — including “Uptown Funk,” “Locked Out of Heaven,” “Grenade” and “If I Knew” — as well as the title track from his most recent release.

Mars first revealed he was shooting Carpool Karaoke via an Instagram post on Nov. 19. His appearance comes less than one week after Corden jammed out with Madonna.
