Kylie Jenner's "Dirrty" Halloween Costume Is Christina Aguilera-Approved

There was no costume idea left on the floor this Halloween season (just as Luna Legend). But one celebrity really kicked it up a few notches. That star is Kylie Jenner and her flawless re-imagining of Christina Aguilera from her iconic "Dirrty" video. From the hair to the chaps to the stripped bikini top, the make-up mogul/reality star got every detail just right.

Yep, she even included the "X" on the bum.

And she had the dance moves down.

And her efforts didn't go unnoticed by Xtina herself, who gave the look a gold-star review.

In case you want to do a little comparing yourself, we've provided the "Dirrty" video for you to play, below.
