Christina Aguilera kicked off Christmas at the happiest place on Earth.
The Grammy-winning singer crooned "Have Yourself a Merry Little Christmas" during Disney's Christmas Day Parade Sunday morning.
And prior to her performance she tweeted about how she gets into the holiday spirit.
"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!
