'Nasty' Barlow told to tone it down

Gary Barlow has been told to give his Mr. Nasty act a rest on ‘The X Factor’.

The Take That singer – who joins Louis Walsh, Kelly Rowland and Tulisa Contostavlos on the ITV1 show’s judging panel – was originally instructed to assume the critical role of Simon Cowell, who quit the series to launch ‘The X Factor’ in the US.
