Harding: 'Paris Hilton is a silly cow'

Girls Aloud's Sarah Harding has hit out at socialite Paris Hilton, calling her a "silly cow".

Harding told The Mirror that she will leave the country if Hilton, who filmed part of her upcoming reality series My New BFF in London, decides to move to the UK permanently.

"If she moved here I would move out as I can't stand to be in the same country as the silly cow," Harding said.

Hilton, who was recently rumoured to be looking for a home in St John's Wood, has described London "as my favourite city in the world".
