Kylie Jenner Gets 'Dirrty' in Christina Aguilera Halloween Costume

Kylie got a little bit naughty with her second Halloween look of the weekend.

Kylie Jenner channeled “Dirrty”-era Christina Aguilera for Halloween on Saturday, and her outfit was everything!

The 19-year-old reality star nailed the costume, rocking the whole signature look from Xtina's 2002 video, including the striped bikini, bleached blonde-and-black hair, and even Christina Aguilera’s infamous cut-out leather chaps.

Even Jenner’s makeup -- smoky eyes and pink lip gloss -- and piercings were on-point reproductions of Xtina's look.

But girl committed to her character, too, busting out a few dance moves on Instagram. “Can I be XTINA forever,” she captioned the video.

On Saturday, Aguilera took to Instagram to give Kylie a shout out. "YAASSSSS".....Killin it @kyliejenner yes to dirrty 2016!! Get it girrrl!!!" she wrote, along with a photo of Kylie in costume.

The Kylie Lip Kit creator took her look out on the town to West Hollywood nightclub Bootsy Bellows, where her boyfriend, Tyga, performed. She documented the night on Snapchat, showing off Tyga’s performance and hanging with her sister, Kourtney Kardashian.
