A full-on trampoline fight has broken out between Khloe Kardashian and sister Kylie, which has left junior Jenner in hospital! It's all fun and games til somebody gets hurt, guys.
Post-accident, the 16-year-old tweeted: "In the hospital thanks to @khloekardashian. (Look at her page for the reason why!) My mum just said 'never thought I would take u to the doctor for a trampoline accident at this age'. This means war Khloe. Ps. It was painful taking this photo."
Khloe's retort to the bouncing brawl? A series of painful Twit-pics of Kylie's fall with the caption: "Kylie this is proof you did it to yourself! Sorry not sorry! Just kidding I am sorry my little bug a boo!! Let the war continue!!!!"
With Kim joining in on the family fun, who knew that the Kardashian clan were big on trampolining?!
This isn't the first time Khloe's embarrassed her sisters! Check out the hilarious video of Kourtney post-dentist below.
