The young star posted a picture of herself covering her face, with the caption, "In the hospital thanks to @KhloeKardashian. (Look at her page for the reason why). my mom 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."
In defense, Khloé posted a picture collage of the two jumping on the trampoline, to prove Jenner injured herself. She captioned the photo, "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!!!!"
In other Jenner news, Kendall Jenner's boo Harry Styles is now being linked to Pat Benatar's 29-year-old daughter, Haley Grialdo.
According to Star Magazine, the 20-year-old One Direction hottie has been seeing Haley off-and-on since last year. A source said, "They met in Los Angeles last year at a One Direction concert and have seen each other on the sly anytime Harry’s been back in town."

The insider added, "I've never heard Harry mention whether Kendall knew he had a thing for Haley. And I get the feeling he didn’t mind all the publicity surrounding their supposed romance."
No word on whether this is true or not, but a pal close to Kendall said if she found out, "she'd be devastated."
