Kylie Jenner went all out for Halloween '16, from pre-gaming as a sexy ghoul to her main event costume: Christina Aguilera from the iconic, not-at-all ironic "Dirrty" video.

The cosmetics mogul shared her look on social media before hitting the party circuit with Tyga (who went as Juelz Santana, along with his crew who each dressed as a member of Dipset) and even did 'Tina's classic dance moves to perfection.

So, did she kill it?

Even Twitter seems to appreciate the effort:

Well done, Kylie.
