Kelly Osbourne has had a row with a man who accused her of being a "sad Kelly Osbourne impersonator".

She was in the queue for the toilets at the Paper nightclub in London when the man made the remarks to her, according to Sky Showbiz.

Osbourne responded angrily, saying: "I am Kelly Osbourne, you American idiot."

The man reportedly walked away from the incident after telling her that he was Canadian.
