Mariah Carey doesn't want a lot for Christmas. We all know this. But on Thursday night's Carpool Karaoke, the diva revealed one thing she longed for: James Corden singing her holiday classic, "All I Want for Christmas Is You."
In a surprise segment of The Late Late Show, Carey and Corden got ~festive~ by hauling a Douglas fir atop their SUV and a bevy of wrapped presents in the backseat. And as they sang, other celebrities joined in.
