Riding around in the California neighborhood of Calabasas, Corden sported a Santa Claus sweater, while Carey donned a red leather jacket with a diamond-encrusted bra underneath. The piece is set to air in December.

Carey would appear to be the perfect guest for a Christmas edition of "Carpool Karaoke," as her 1994 album, Merry Christmas, is the best-selling Christmas album of all time and her first "Carpool Karaoke" appearance has nearly 28 million views on YouTube.

The Late Late Show airs weeknights at 12:37 a.m. ET/PT on CBS.
