Kylie Jenner has been treated in hospital after she was injured while trampolining with her sister Khloe Kardashian.

The 16-year-old later posted a photo on Instagram showing her covering her nose and said 'it was painful taking this photo'.

She added: '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) this means war Khloe.'

However, her big sister Khloe hit back on her own Instagram account, saying: 'This started out calm and ended in war! Sorry @kylie jenner'.

She added: '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!!!!'

Khloe also posted images that appeared to show Kylie had hurt her back, rather than her nose in the accident.
