X Factor judge Kelly Rowland has reportedly told friends the atmosphere backstage on the show is becoming unbearable, due to her frosty relationship with fellow judge Tulisa Contostavlos.

According to the Sunday Mirror the Destiny’s Child singer – who missed Saturday night’s show due to being unwell with a throat infection – has called the show a “living hell” and is ready to swap seats on the panel so she is not sat next to Tulisa, unless their relationship improves.

Reports over the weekend have suggested that the pair have not spoken since the N-Dubz singer publicly accused Kelly’s contestant Misha B of bullying her acts – later revealed as members of girl band Little Mix – backstage.

“Tulisa and I have no relationship,” Kelly is reported to have told a friend. “The show has become a living hell. I don’t know how long I can tolerate this for.”

“None of Tulisa’s acts go anywhere near Kelly’s on set,” a source added.

Kelly was told to ‘stay out of it’ by Tulisa when she ­offered advice on her acts two weeks ago and it’s been frosty between them ever since. Kelly’s just not used to this infighting and bitching.

“She’s feeling ­extremely ­uncomfortable with ­Tulisa and doesn’t feel like she can ­approach her to make amends – it’s like ­Dannii Minogue and Sharon ­Osbourne all over again.”

The source also said that Kelly had been having talks with Simon Cowell to discuss how the situation could be resolved.

“The past two weeks have been hellish. Simon has had to work hard to stop her jacking it all in. But Kelly is no pushover, and can easily look after herself.”

Kelly – who jetted to Los Angeles following last weekend’s row – missed Saturday night’s show after being laid low with throat trouble, and being told by doctors she was too sick to travel.

Meanwhile Gary Barlow admitted he was “shocked” by Tulisa’s outburst last Saturday, which was followed by Louis Walsh making similar claims against Misha.

Maybe it’s a case of Kelly and me against Louis and Tulisa.

“I don’t know why Tulisa did it,” he told the Sunday Mirror.

“But she is the kind of person who only does stuff she believes in. She’d pobably defend it if you talk to her. Tulisa’s not one to back down.

“We all feel very protective towards our acts. In Tulisa’s eyes she was ­defending her bands, but then on the other side of the coin Kelly’s there with one of her bands being looked at like a trouble maker.

“If anything I think Misha’s chances will have improved,” he added. “I think people will have felt sorry for her.”
