Walsh annoyed by Cowell's 'X Factor' joke

Louis Walsh has been left unimpressed by a joke played on him by fellow X Factor judge Simon Cowell.

Cowell gave Walsh's mobile phone number to a fan live on the ITV1 singing contest.

"This is Simon's idea of a joke," Walsh told The Mirror.

Since, the music guru has been inundated with messages asking for a rendez-vous from audtionee Shirley Hough, 50, from Rugby.
