Kim Kardashian has reportedly filed a police complaint after she was ambushed by a prankster as she entered a restaurant in Paris, Sky News reports.

Footage shows the reality star walking past photographers when a man in sunglasses suddenly lunges forward and seemingly attempts to kiss her bottom.

Vitalii Sediuk was quickly pulled to the floor by a security guard.

This is the second time that Sediuk, a former Ukrainian television reporter, has targeted Kardashian.

On Instagram, he claimed his stunt was in protest at Kardashian's use of cosmetic surgery - and called on her family to "popularise natural beauty among teenage girls who follow and defend them blindly".

Sediuk also insisted that his attack was unplanned, adding that he was merely eating ice cream outside the restaurant and did not know Kardashian was going to be there.
