Kris Jenner Has A Nip Slip In Her Wonder Woman Costume

Over the weekend Kris Jenner tweeted this photo of her Halloween costume, but after realizing that she accidentally included a peek at her nipple, she deleted the shot. Of course, Khloe didn't want to let her forget, as she re-tweeted the shot and added, "Hi nips. That's my mom."

Looks like Kim's gonna have to step it up to compete with her mother!
