Kylie Jenner wears skimpy Christina Aguilera-inspired costume

Kylie Jenner slayed in her super revealing Christina Aguilera costume on Halloween, so when the pop superstar’s birthday bash rolled around Sunday, Aguilera asked her to friend reprise the role.

Jenner arrived at Aguilera’s party in the yellow and black bikini top and chaps,  which were memorably worn by the singer during MTV’s “TRL Presents: Christina Stripped in New York.”

The 18-year-old reality star captioned one of her many posts, “When XTINA wants u to dress as XTINA for her bday, you do it!!"

Inspired by Xtina’s 2002 “Dirrty” music video, Aguilera requested the “Keeping Up with the Kardashians” star to reprise her famous costume for her event.

The birthday girl wore a multicolored fur coat, an epic pink wig and bejeweled glasses. She was captured via Instagram canoodling with the young reality star.

Jenner came with a couple of her closest buddies -- Los Angeles socialite, Jordyn Woods and celebrity private tutor, Tiffany Sorya.

After a long night of dancing, Jenner and her gal pals did a costume change of their own from sky-high heels and skimpy garb to comfy animal-print PJs, complete with claw-foot slippers.
