John Legend and Mariah Carey

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).
