Singer Nicole Scherzinger got so annoyed with Simon Cowell’s meddling with her team on The X Factor that she has banned him from attending rehearsals for her team members.

Cowell, 52, had been attending the singer’s team-mate Stacy’s rehearsals and criticised Scherzinger’s work. He also took credit for choosing Stacy’s song on last Wednesday’s episode. According to an insider, the former flame of British Formula 1 driver Lewis Hamilton spent the weekend in seclusion, mentoring her team with the Simon ban. “Last week, Simon made a big deal out of choosing Stacy’s song, and he said he didn’t think she’s connected with them all,” Radar Online quoted the insider as saying. “Now, she’s made it clear these are her artists, she is mentoring them and Simon should back off!” the insider added.
