Khloe Kardashian and her 16-year-old sis Kylie Jenner were having some fun on the trampoline, when a bit of an incident occurred. Kylie must have fallen somehow, and after a series of pics laughing and jumping, it then turned into the above photo with the caption, “In the hospital thanks to @khloekardashian. My mom said ‘never thought I would take u to the doctor for a trampoline accident at this age.’ It was painful taking this photo.” Couldn’t have been TOO bad, though. “Kylie this is proof you did it to yourself! Sorry not sorry,” Khloe then posted. “Just kidding I am sorry my little bug a boo!! Let the war continue!!!!” Check out the pics in the gallery!
