Although the brunette never specified how the injury occurred, she shared a classic Kimoji of herself crying alongside the online post.

The news comes just less than a week after the Keeping Up With The Kardashians star enjoyed a movie night at Sacha Baron Cohen and Isla Fisher's house. Kim was joined by husband Kanye West, Kourtney Kardashian, Kris Jenner and Courtney Cox for a screening of the comedian's new movie The Brothers Grimsby.

Kim uploaded a picture of the gang on her Instagram page for her 62 million followers to see. "About last night," wrote the star.

At the back of the photo, Courteney's daughter Coco was also in the mix among the many famous faces. The only child of the Friends actress and ex-husband David Arquette, who isn't often photographed, looked very grown up in a black tank top with her hair half-up, half-down.

"This was the moment right before Sacha showed us the CRAZIEST scene from The Brothers Grimsby. We laughed so hard we cried!"
