Mariah Carey has teamed up with sexy crooner John Legend for the holiday duet "When Christmas Comes."

In the video, a very svelte Mimi, 41, and hubby Nick Cannon, 31, show off adorable eight-month-old twins Monroe and Moroccan. So great to see Mariah's curly hair back in action, too!

Looks like the Christmas spirit is alive and well in the Carey/Cannon home!
