Cheryl performed her new single I Don't Care on the X Factor results show tonight (November 2).

The 31-year old swapped the judging panel for the stage to sing her new track, dazzling the crowd in a revealing sheer white top, hot pants and shirttied round her waist -completing her lookwith thighhigh white boots.

Fellow judges Simon Cowell, Mel B and Louis Walsh were clearly impressed by her performance, giving the star a standing ovation, with Cheryl later telling host Dermot O'Leary she felt "nervous",but added: "It's healthy to be nervous."

Despite the song only being released at midnight,I Don't Care is already No.1 on the UK iTunes chart, and if Chezza manages to topple Ed Sheeran from the Official Single Chartsummit next week, she'll become the first UK female to score five chart-topping hits.

Despite the song already blasting its way to the top of the download countdown,Cheryl previously told MTV News that she isn't bothered about chartpositions.

"It's just about putting out music that you believe in and that you love and sending out a message that you want to send out."
