Kylie Jenner reprised her 'Dirrty' Christina Aguilera look for Xtina's own birthday party

There's clearly something about Xtina for Kylie Jenner: In a reprise of her killer Halloween costume this year, Jenner dressed up as Christina Aguilera yet again—this time, for the pop sensation's own birthday party.

Prior to the event, Jenner teased on Snapchat, "We are about to start glamming for something that I'm really excited about." Little did we know, she'd be breaking out the blond-and-black streaked wig for another night of dressing up as Aguilera from her 2002 video "Dirrty." But she switched up the look a little: For Halloween, Jenner wore a red-and-white striped bikini top with black-and-red chaps ensemble. This time around, the reality star opted for a black-and-yellow look from the unforgettable music video. She even rocked blue contacts for the occasion.

And later, we were all treated to a photo and video of Kylie Xtina and the real Xtina, who turns 36 on Dec. 18, at the bash. Not to be outdone, Aguilera had on quite the outfit herself—The Voice coach rocked a wig of cotton-candy-like pink hair, a furry multicolored coat, and super sparkly shades to go along with her signature red lip and cat eye. "Birthday Bae," Jenner captioned the pic of the two.

Here's a look at Kylie's full outfit—along with friends Tiffany Sorya, who donned a leopard jumpsuit for the party, and Jordyn Woods, who looked the part of a "Genie in a Bottle" in her lavender, sequined dress and jewels adorning her forehead.

From the looks of it, Jenner (and the rest of Xtina's guests) had a great time. Kylie shared a few snaps from the dance floor to prove that she and her crew had the moves to match the look.
