Mary J. Blige brought the Christmas spirit overseas. On Sunday, the Queen of Hip-Hop Soul joined forces with British darling Jessie J to perform their duet “Do You Hear What I Hear?” on “The X Factor” U.K. The ladies showed off their powerful pipes, while Jessie traded her blonde hair for black locks.

The song can be found on Mary’s holiday album A Mary Christmas.

Celebrate the season with the big-voiced divas.
