We cannot WAIT to see the divalicious Mariah Carey belt it out for Carpool Karaoke in James Corden's Range Rover!

OMG, what are they gonna sing? We want "Vision of Love," "Fantasy," "I Don't Wanna Cry," "Butterfly" -- there are so many!!! Those two could have been in the car together for HOURS hitting all the high notes of Mariah's career.

Carey wore a skin-tight red leather biker jacket with who knows what underneath -- diamond-crusted lingerie?! Whatever it is, we love it -- it's classic Carey. Meanwhile, Corden wore an ugly Christmas sweater, so we bet there are some Christmas carols in store for us in this Carpool Karaoke.

Corden showed up to Mariah's Calabasas mansion with a Christmas tree in tow; then the two went out for dinner at Lovi's Deli. This is really getting us into the Christmas spirit, now if only it weren't 100 degrees in LA!
