Christina Aguilera took to social media on Wednesday (Dec. 16) to spread a bit of the holiday spirit with her famous pipes and some help from Buddy the Elf.

Dressed head-to-toe in a festive plaid pantsuit by Vivienne Westwood and extra-long high pony while standing in front of a massive Christmas tree, the singer kicked off her TikTok by lip syncing along to the Code of the Elves from 2004's Elf. "The best way to spread Christmas cheer is singing loud for all to hear," she mouthed over Will Ferrell's voice,

From there, Xtina unleashed a powerful riff that sounds surprisingly similar to the one she sang at the beginning of 2010's "Show Me How You Burlesque" — only this time, the message was a holly jolly "Happy Christmas."

While the fun TikTok moment was her first since Halloween, it arrived just one day after the pop star dusted off her melismatic version of "The Christmas Song" to celebrate the 20th anniversary of her sole holiday album, 2000's My Kind of Christmas, with a special performance on Late Night with Seth Meyers. ("Merry XMas to you," she wrote while sharing the performance on her Instagram and Twitter feeds.)

Released one year after her smash self-titled debut album, Xtina's Christmas LP debuted at No. 38 on the Billboard 200, peaking at No. 28 and being certified platinum by the RIAA. Her take on "The Christmas Song," meanwhile, became her fifth consecutive top 20 hit on the Hot 100, following her three No. 1s ("Genie in a Bottle," "What a Girl Wants" and "Come On Over [All I Want is You]") and "I Turn to You," which landed at No. 3.
