Simon Cowell labelled Gordon Ramsay 'fat' when the X Factor judge appeared on an episode of Top Gear.

TV's Mr Nasty insulted the Wandsworth celebrity chef during a chat with presenter Jeremy Clarkson on the BBC Two motoring show last night.

Cowell is now top of the programme's celebrity leader board after completing a lap in a Chevrolet Lacetti in the fastest time yet.

He pushed Ramsay into second place and said the Scot's weight probably added 'a couple of seconds' to his lap time.
