Just weeks after being elbowed in the face by supermodel Gigi Hadid, Ukrainian prankster Vitalii Sediuk is at it again.
This time he has snuck up on Kim Kardashian and kissed her bottom at Paris Fashion Week.
Ms Kardashian's make-up artist caught the episode on tape but fortunately for Mr Sediuk, Kim didn't react as strongly as Gigi did.

Vitalli says he did it to protest Kim using fake butt implants.
"I encourage her and the rest of Kardashian clan to popularise natural beauty among teenage girls who follow and defend them blindly."
