The judge admitted during auditions for the current series that rejecting Monica Michael last year was one of the worst mistakes she made during her time on the panel and was thrilled when the youth worker returned this year.

Last year Cheryl received boos from the audience for her decision to cut Monica during the controversial six-chair challenge while co-judge Simon Cowell was also shocked by it.

Speaking to the panel, Monica said: "I would be lying if I said my confidence didn't get knocked."

And she can be seen on screens performing a rousing rendition of Christina Aguilera's 'Impossible'.

Also returning is Jade McGuire, a 30-year-old receptionist and single mother-of-two from Glasgow.

Rita Ora told her: "I love it when I see independent women take control of their own destiny, I think it goes to show that sometimes we don't always need men, and sometimes all we need is a bit of love and a bit of belief."

'The X Factor' airs on ITV1 on Saturday at 8pm.
