*Dem Babies have made their music video debut in the latest video from their mama Mariah Carey.

Eight-month-old twins, Moroccan and Monroe, join their daddy Nick Cannon in the footage for “When Christmas Comes,” her duet with John Legend.

The video – much of which has been shot in a vintage, grainy Super-8 style, to look like an intimate home recording – shows the twins, inter-spliced with footage from old “Peanuts” cartoons and scenes of her singing to a family gathering, accompanied by John Legend on piano

The track ‘When Christmas Comes’ was originally recorded for Mariah’s 2010 album “Merry Christmas II You,” but the singer decided to re-record it as a duet with Legend.
