Girl's Aloud star Sarah Harding has slammed Paris Hilton, branding the socialite a “silly cow”.

The singer threatened to leave the UK if Hilton, who recently shot a TV series in London, ever moved permanently to the country.

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