Christina Aguilera had one birthday wish that Kylie Jenner was more than happy to facilitate: dressing up as her (again).

This past Halloween, Jenner proved that her impersonation of the singer is absolutely on-point, recreating Aguilera's 2002 look from the music video for the hit single "Dirrty." The singer was so ecstatic about having Jenner as her mini-me that she requested Jenner dust off her throwback threads once again for the special occasion.

For her second time dressing up as Aguilera, the 19-year-old reality star rocked a black and yellow bikini top, X-Tina-style chaps, blue contacts and, of course, blonde hair adorned with black streaks.

The outfit, although different than Jenner's Halloween costume, takes us back to Aguilera's "Dirrty" phase one more time. Judging from the SnapChats and Instagram posts from last night's star-studded party, the soon-to-be 36-year-old was proud to see the youngest Jenner sister doing her signature style justice.

Aguilera's actual birthday is the 18th, and we have a feeling Jenner just might have a third tribute look already picked out. You know, for the 'gram.

Take a look at Kylie Jenner dressing up as Christina Aguilera, per the singer's request, in the various posts below.
