While sleigh bells were jingling and ring-ting-tingling, Christina Aguilera [1] was busy bringing down the house on Late Night With Seth Meyers [2] with her cover of "The Christmas Song," made famous by Nat King Cole. Posed in front of a festive winding staircase and a Christmas tree dressed to the nines, Aguilera eased into the soothing melody before ripping into every high note with the force of a 100 flying reindeer.

After watching this performance for the fifth time in a row, we still have chills (and it has nothing to do with the snowy weather). Listen to Aguilera's stunningly beautiful performance here and check out her fellow The Voice alum Kelly Clarkson [3]'s rendition of "Have Yourself a Merry Little Christmas [4]" to dive even deeper into the holiday spirit.
