We always knew she had a naughty side!

Kylie Jenner took home the crown for best costume this Halloween after dressing up as Christina Aguilera, circa 2002.

Yes, even though back in the day when Xtina wore leather chaps and killer braids on the daily, Kylie was just FIVE YEARS OLD, she still managed to effortless work the look like a pro.

The KUWTK star even gave fans a treat by performing a Dirrty inspired dance on Instagram. Iconic.

Kylie enjoyed her night out in Los Angeles with boyfriend Tyga, but things apparently got super awks when the pair bumped into fashion designer Imogen Anthony, who just happened to be wearing a near-identical costume to Kylie’s!

Meanwhile, Little Mix’s Perrie Edwards looked ravishing as a redhead when she decided to dress up as Poison Ivy. Strong look, Pezza.

Demi Lovato and Nick Jonas truly shone with their interpretation of Dorothy and the Scarecrow from The Wizard of Oz.

Former TOWIE star Ferne McCann decided to channel her inner spirit animal and spend the evening partying as Ferne the Fox. Stunnin’.

Nice work, guys.
