We were quite puzzled as to why Nicole Scherzinger didn't step in for Kelly Rowland yesterday, but it now appears the reason was Simon Cowell. According to The People, the X Factor boss felt that Nicole guest judging the show for the weekend would "degrade" her.
In the end it was Alexandra Burke who stepped into the role after Simon stopped X Factor USA judge Nicole from appearing at the last minute.
A source said: “[Nicole] was so happy to step in to help but Simon didn’t want her joining it.
"He thought it might degrade her.”
