Tonight Dermot O’Leary  revealed that The Wanted, Nicole Scherzinger and Justin Bieber will perform on next Sunday’s X Factor results show.

 The worlds most popular teen sensation Justin Bieber will get the girls screaming even more than  One Direction in next week’s results show. This will be his first time on the X Factor and if his performance on American Idol earlier this year is anything to go by, Simon might have to double the security around the stage.

Nicole has featured heavily in this year’s series. After Dannii Minogue fell pregnant and Cheryl Cole contracted malaria, Simon brought the Pussycat Doll in to assist himself and Louis Walsh in the Manchester auditions and later she return to help them  at bootcamp.

The Wanted made an appearance on The Xtra Factor on ITV2 last night where most of the band seem to be backing One direction and Matt Cardle. They are expected to sing their latest single ‘Lose My Mind,’ from their self titled debut album which is planned for release in early 2011.
