"I love the holidays," Aguilera tweeted. "Great time to dress up & celebrate. Party dress, red lips & one of my fragrances always makes me feel festive. XOXtina."

As you can hear from the performance, she really knows her way around this tune, which shouldn't be a huge surprise. Back in 2000, Aguilera released her own Christmas album called My Kind of Christmas, which includes "Have Yourself a Merry Little Christmas" among other traditional holiday songs. Sweet!
