James Corden is still adjusting to his new gig as host of CBS' Late Late Show, but he's already finding that the drive to work can be long and a little lonely.
Fortunately for the late-night newcomer, Mariah Carey was more than happy to ride shotgun! The Grammy winner even joined her British buddy in singing karaoke in the car—to the tune of her own hits!
Mariah was hesitant at first, telling James, "I'm not singing today. I was up all night!" But when "Always Be My Baby" just happened to come on the radio, she couldn't resist singing along!
