Need a little extra boost to get into that holiday spirit?

Luckily, Little Mix are here to bring some "LittleMixmas" cheer with their rendition of "Christmas (Baby Please Come Home)."

Dressed in their finest Christmas attire, including some cheesy light-up sweaters, the girls open the classic track, which was once recorded by Mariah Carey, singing a cappella in perfect harmony.

As the music kicks in, so do the laughs, as the girls -- Jade, Perrie, Leigh-Anne and Jesy -- invite some of their Mixers to join in on fun. Surrounded by fans in Santa hats, they continue to sing, dance, play instruments and look like they are having the best time ever.

This isn't the first cover song the girls have done. The recently created an epic version of Beyonce's “7/11″ complete with twerking, stuffed animals and synchronized dance moves. Bey would be proud.
