Cowell and Walsh want Scherzinger for 'X-Factor'

Simon Cowell and Louis Walsh are desperate for Nicole Scherzinger to help them during the Judges' Houses 'X Factor' round.

The competitive pair are said to be battling it out to convince the Pussycat Dolls singer – who appeared on the show as a guest judge earlier this year – to join them in the next stage of the competition, and help them decide who makes it through to the live stage of the competition.
