Stony faced Cheryl Cole and Dannii Minogue snubbed star guest Jay Kay on last night's X Factor after he called them f****** useless.
The pair studiously ignored his performance of comeback single White Knuckle Ride, with Dannii reportedly even playing noughts and crosses with her fellow judge Louis Walsh.
The panel which usually gives visiting stars a standing ovation stayed firmly seated and refused to clap. Eventually Louis and Simon applauded.
Less than 24 hours before appearing in front of the panel Jay Kay criticised the show saying, "I just don't like the w**** stuff I have to do. F****** X Factor and that."
He went on to question Cheryl and Dannii adding, "What the f***. When have you ever done anything? I mean you look great and I'd like to f****** s**g you but that's all."
The atmosphere backstage was reportedly, 'extremely awkward.'
