If you've been missing Mariah Carey lately (did Christmas even happen this year? Where were the instagram robe photos? The seasonal Aspen Jacuzzi photos?), she's baaaaaack. Late Late Show host James Corden got Mimi to ride around L.A. with him while they blasted her music and sang along to her hits for a segment called "Carpool Karaoke" and the whole thing is just delightful. Watch above.
