VIDEO Did Cheryl Cole and Dannii Minogue blank Jamiroquai star Jay Kay on The X Factor?
The 2 female judges remained seated after the singer's performance of White Knuckle Ride and didn't even clap.
It's thought Cheryl, 27, and Dannii, 39, were upset with Jay Kay after he reportedly launched into a rant about them.
'[They're] f***ing useless,' he was quoted as saying in The Sun.
'What are they going to tell me about f***ing music? When have you ever done anything? You're useless. I mean you look great and I'd like to f***ing shag you but that's all.'
Jay Kay, 40, played down the controversy while talking to Dermot O'Leary after his performance.
'I had reservations about coming on the show,' he said. 'But I've had a great time.'
