On Set of Mariah Carey and John Legend's 'When Christmas Comes' Video

Christmas came a month early for Mariah Carey and John Legend. The Grammy-winning duo brought the snow to sunny Southern California over the weekend while shooting the festive video for “When Christmas Comes,” a remake of the holiday tune that originally appeared on Mariah’s 2010 album Merry Christmas II You.

Roc and Roe’s mama showed off her post-pregnant body in red, joining Legend at the piano to duet on their collaboration. A snow-covered lawn and Christmas tree in the living room added to the merry mood. Nick Cannon dressed as jolly old Saint Nick and Legend’s girlfriend, Christine Teigen, tweeted pictures of him on set.

Get in the spirit by checking out some behind-the-scenes pics from their holiday house party.
