The 19-year-old reality star dressed herself in the iconic costume from the 35-year-old singer's music video for 'Dirrty', and now the musician has given the costume her seal of approval.
Posting a picture of the 'Keeping Up with the Kardashians' star on her Instagram, Christina wrote: ''YAASSSSS''.....Killin it @kyliejenner yes to dirrty 2016!! Get it girrrl!!! (sic)''
Meanwhile, Kylie posted a video of herself dancing to the 2002 hit single whilst in her costume, which saw her sport a bikini top, with red leather flared trousers.
She captioned the photo: ''Can I be XTINA forever (sic)''
In total, the beauty posted nine pictures on the photo sharing website of herself in the raunchy attire as she headed out to a party with her boyfriend and rapper Tyga.
One photo was captioned with the lyrics from the song which read: ''Dirty, Filthy, Nasty, you nasty yeah. Too dirty to clean my act up...If you ain't dirty..You ain't here to partyyyyy whooo (sic)''
The decision to channel the 'Genie in a Bottle' hitmaker for Halloween comes after Kylie recently revealed she would love to be able to sing.
She said: ''It's no secret I love music, especially everything we play on Kylie Radio. And I have some crazy talented friends with beautiful voices, like Justine Skye. I really would love to be able to sing!!!
''It's the one talent I wish I had. Yeah, I've kind played around (did you catch me singing Solange's 'Cranes In The Sky' on Khloé's Snapchat?
''But to be able to really, really sing would be such a dream. Jordyn [Wood] says I can, but isn't that what best friends are supposed to say?''
