Trampolines are dangerous at every age!
Khloe Kardashian may be pushing 30, but today she and 16-year-old Kylie Jenner had an all-out war on a trampoline -- and it didn't end so well for Kylie.
The older reality TV star started sharing some photos from their day jumping around -- and it seemed innocent at first.
Then ... something happened. And judging by the photo below -- which Khloe posted -- it looks like Kylie may have hurt her back.
"Kylie this is proof you did it to yourself! Sorry not sorry," she posted with the pic. "Just kidding I am sorry my little bug a boo!! Let the war continue!!!!"
"In the hospital thanks to @khloekardashian," Jenner posted on her own Instagram -- along with the top pic, suggesting she also hurt her face. "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," she added about her selfie.
Whoever was to blame, Kylie's accident didn't ruin the fun for the rest of the family. Shortly after, Kim Kardashian posted her own photo on the trampoline with Khloe, jumping around without a care in the world.
