Barlow and Walsh 'at war'

Gary Barlow and Louis Walsh are said to be "at war".

The 'X Factor' judges - who have repeatedly clashed throughout the ITV1 competition - are reportedly no longer on speaking terms after Louis slammed Gary's act Frankie Cocozza as "bad karaoke" and the Take That singer was less than complimentary about Kitty Brucknell and Johnny Robinson's efforts on Saturday night's show.
