'X Factor' act advised to ignore Louis

Girls Aloud have told X Factor finalists Same Difference to ignore their former manager Louis Walsh.

The pop five-piece were formed on 2002's Popstars: The Rivals - a forerunner of The X Factor - on which Walsh appeared as a judge.

Walsh proceeded to manage the record-breaking girl group until 2005, but Girls Aloud were quick to side with Same Difference in their long-running feud with the pop svengali.

"Louis is going to hate [your performance], so ignore him and put your fingers in your ears," they told the brother/sister duo. "Maybe he's doing you a favour. You've got the 'e' factor – the entertainment factor – so camp it up, because you can get away with it."
