Christina Aguilera and her guests gave zero f***s when it came time to celebrate the singer's 36th birthday. From the star-studded guest list — Kylie Jenner as vintage Christina Aguilera (per the singer's request after Kylie's incredible Halloween costume) and The Real Housewives of New York City's Bethenny Frankel — to the incredible performance (we'll get to that), the party was obviously off-the-hook.
Did we forget to mention that Erika Jayne even performed?
Heck, even Santa looked more naughty than nice at the bash. Perhaps having a latex-clad Bethenny on his lap inspired the mood.
Xtina simply slayed in her outfit, which looks like it was inspired by the board game Candy Land, Marie Antoinette, and Elton John.
