will.I.am has revealed that 'X Factor USA' judges Cheryl Cole and Paula Abdul gang up on boss Simon Cowell.
The Black Eyed Peas star claimed that they find it funny to wind up the music mogul.
He told The Sun newspaper: "They worked out pretty quickly that it's funny to annoy Simon, but even funnier if they gang up and do it together.
"Simon used to have Cheryl to put up with on The X Factor and Paula on American Idol, but now he has to cope with them together."
However, will.I.am insisted that Cowell enjoys their taunting, saying: "They are not letting him have an easy ride, but he loves it really."
The singer also suggested that Cole may return to the British version of the show as it is her "first love".
He said: "It would have been impossible for them to do it this year, but I wouldn't rule out Cheryl and Simon both returning. The UK X Factor is Cheryl's first love."
