Mariah Carey Sings Carpool Karaoke on 'The Late Late Show'

Mariah Carey helped welcome the new host of “The Late Late Show,” James Corden, to L.A. with some carpool karaoke. The Brit got behind the wheel of his Range Rover and rode around L.A. with the pop diva in the passenger’s seat. They passed the time by singing some of Mariah’s biggest hits including “Always Be My Baby” and “Vision of Love.” James rapped Ol’ Dirty Bastard’s part on “Fantasy” before capping off the joyride with Mariah’s Hit-Boy-produced single “Thirsty.”

Mimi, who celebrates her birthday tomorrow, also had some fun playing with British and New York accents.

A reissue of her greatest hits album #1’s will be released in May to coincide with her Las Vegas residency, which kicks off May 6 at The Colosseum at Caesars Palace.

Watch Mariah ride around while belting out her hits.
