John Legend and Mariah Carey

Mariah Carey and John Legend to Throw House Party in Christmas Video

Earlier this week, Mariah Carey revealed that she had teamed up with John Legend for a remix of her Christmas song. Now the pop diva is revealing plans for the festive video.

Carey duets with Legend on “When Christmas Comes,” the James Poyser-produced cut that originally appeared on her 2010 holiday album Merry Christmas II You.

“One of my favorite artists for the past few years, John Legend, and I just did a duet on a song called ‘When Christmas Comes’ that I wrote last year,” said Mariah on “The Rosie Show.” “So he’s singing with me and we’re doing the video in L.A.”

Monroe and Moroccan’s mother offered a teaser of what to expect from the video. “It’s gonna be more of a house party than a real video. So it will be like having Christmas early and being festive.”

During her visit to “Rosie,” the singer also showed off her trim post-baby body and announced that she is the new spokeswoman for the Jenny diet plan (formerly Jenny Craig).
