Like many big sisters, Khloe Kardashian has a tendency to roughhouse with her younger siblings, as fans of Keeping Up With The Kardashians have probably seen. Well, now it looks like all that horseplay has landed half-sister Kylie Jenner in the hospital — possibly with a broken nose!

“In the hospital thanks to @khloekardashian,” the 16-year-old’s Instagram caption begins. In the photo, Kylie cups her nose and eye with a well-manicured hand and advises her followers to look at Khloe’s feed if they want to know the reason why she’s currently waiting to see a doctor. Looks like what started out as a friendly chicken fight on an extra-large trampoline ended in a trip to the ER!

But if you’re expecting remorse from Khloe, you’ve got another thing coming. “Kylie this is proof you did it to yourself! Sorry not sorry!” Khloe taunts from her Instagram. “Just kidding I am sorry my little bug a boo!! Let the war continue!!!”

While Khloe’s not standing down, we’re pretty sure mom Kris Jenner would like to call a ceasefire. “My mom said, ‘Never thought I would take u to the doctor for a trampoline accident at this age,’” Kylie writes. A mother’s work is never done, Kris — especially with a bunch as rowdy as those girls!
