Christina Aguilera’s Christmas Spirit Is Next Level

There are so many things people do to get in the holiday spirit — whether it’s as simple as sipping eggnog at a party, rocking an ugly Christmas sweater, or putting those (weird) antlers and Rudolph nose on their car. Christina Aguilera’s love of Christmas is bigger than that, though. She apparently has an entire closet of sexy holiday-themed outfits, and she’s putting them to good use this month. (What? It’s not like she can wear them in July.)

On Sunday — the day the “Dirrty” singer turned 36 — she shared an Instagram photo featuring her and her husband, Matt Rutler, in How the Grinch Stole Christmas-themed outfits. While he was unrecognizable beneath his green mask in a fug sweater, you couldn’t miss Aguilera. The pop star was a super-sexed-up version of little Cindy Lou Who (who knew that was a thing?) in a skintight pink dress with fur around the low-cut neckline and red hot lips. Her hands-on-the-hips pose completed the look.

Hey, it was her special day. Mrs. Grinchmas could wear the “birthday suit” of her choosing, right? That’s true, but lately she’s been all about the sexy Santa-type looks. On Friday, Christina, a mom of two, squeezed into a curve-hugging red catsuit as she posed next to a garland-adorned set of wheels. “Nice,” The Voice personality captioned the photo in which she had one finger seductively in her mouth.

She quickly got “naughty” though. She threw her arms in the air, smacked her lips, and stuck out her booty for a counterpart pic.

All those photos are downright demure next to the ones from her birthday party, which took place on Dec. 10 (and at which Kylie Jenner was a guest). There was a little of this:

A dash of that:

And some of … well, then:

All of these looks are enough to make ol’ Santa Claus (and the missus) blush, aren’t they? But let’s not forget this is the girl who had an assless-chaps era. Xtina knows how to do racy.
