KELLY ROWLAND has sparked rumours that singer and former bandmate, Beyoncé, could perform at the X Factor final.

The X Factor judge said that she would "love" to have Bey attend the grand final of the ITV1 talent show, despite the pregnant star turning down the opportunity to assist Kelly in picking the finalists at the Judges' Houses stage due to her packed schedule.

Kelly, who was chosen to be the mentor for the girls category in the competition, told new! magazine:

"I'd have loved Bey there at Judges' Houses, but she has a tight schedule and she's pregnant."

She's still a great support though from the US, and if it's possible I would love to have her in my corner for the final."

"There is enough talent in any [girls] category to win it, but the girls are a little bit special this year. It's the girls who moved us all to tears. I honestly think we have a girl who can sell millions of records," she added.

The 30-year-old also revealed that she is expecting "fireworks" between her fellow judges, Tulisa Contostavlos, Gary Barlow and Louis Walsh, once the live finals begin later this year.

"Up until now we've all been on the same side, but when it's the live  finals, and we have our own acts to defend, you'd better know there are going to be fireworks!," she said.
