The 42-year-old reality star took the hilarious moment in stride, posting a selfie with the birthday girl to her Instagram Stories, writing, "That time I showed up to a birthday dinner in full costume when it wasn't a costume party! Happy Birthday to the most beautiful kind soul @traceeellisross."

Kim, who is known for her Halloween looks, didn't hold back dressing as the X-Men character in an all-blue body suit, heels, and matching face makeup. She wore slicked back red hair to complete the look. 

The anti-hero role has been portrayed by both Kardashian pal Jennifer Lawrence and Rebecca Romijn in the X-Men films. 

Kim also posed with friends Olivia Pierson and Natalie Halcro, captioning their looks, "Magik, Mystique, Selene."

She also shared a selfie with Diddy, who went all out channeling Heath Ledger's The Joker from The Dark Knight
