This'll make you do a double take!
Kylie Jenner first donned her best "Dirrty" Christina Aguilera outfit for Halloween, and the 19-year-old reprised the look for the singer's birthday bash over the weekend.
In honor of the star's 36th birthday, Kylie once again tried out the mother-of-two's sexy persona from her 2002 music video.
Just a couple of months ago, Christina took to Instagram to approve of the Keeping Up with the Kardashians star's costume, and clearly loved it once again, according to Kylie's Snapchat story.
The two can be seen embracing during the party, and it's clear that the birthday girl was all for the impressive impersonation.
