Carol Decker has branded Gary Barlow a "twat" on Twitter after he said it was "nice" to hear her song "sung in tune" live on Saturday's X Factor performance.
"I remember the original song and it was also nice to hear that sung in tune", the Take That member told Amelia-Lily after her rendition of China In Hand, originally sung by Decker.
The T'Pau singer then took to Twitter to vent her anger, writing: “Gary Barlow you t**t! & I had to suffer a Take That concert for the sake of my kids this summer.
“What’s your f**king problem ? I actually have perfect pitch”, she scathingly added.
But, she deigned to defend her new nemesis, telling one Twitter follower: "Now now don't be unkind, he's lost weight & taken dance lessons".
Take that, Barlow. Miaow!
