Mariah Carey just welcomed her twins in April, but she is already back to work. Bringing her seven-month-old twins Moroccan and Monroe along, the 41-year-old singer shot her “When Christmas Comes” video with her husband and with John Legend on the piano.

The sweet video shows quick shots of Nick Cannon holding one of the babies and dancing and documents them celebrating with their families.

Carey is featured on Justin Bieber’s Under the Mistletoe Christmas album, which debuted at the top of the charts. They do a duet of her "All I Want for Christmas Is You," which she originally released in 1994.

She tells UK's The Sun, "I'm amazed and humbled by its popularity, even all these years later. And I think it's great that people have the song as a ringtone. Who'd have thought, all those years ago when I wrote it, that it would still be having an impact today?"
