The X Factor judge Dannii Minogue has denied reports that she has been sacked by singer Rachel Hylton.

According to the Daily Mirror, 26-year-old Rachel had rejected Danni as her mentor after she finished in the bottom two acts last weekend.

A source from the show told the Mirror: “There is total breakdown in communication between the two girls with Rachel ultimately feeling Dannii is failing her. She is desperate to win the competition, but she feels she has no chance if Dannii keeps giving her the wrong tracks to perform.”

But both Dannii and Rachel deny they have parted ways. Dannii said on Wednesday: “Rachel and I have not fallen out and there has never been any discussions that she wishes to leave Team Minogue.”

Rachel added: “Dannii and I talked yesterday and I don’t have anything against Dannii at all. I respect her opinions, all I want is a little more control over my performance and styling, which she is allowing me to have.”

But Dannii has admitted she has struggled to build a working relationship with the mum-of-five. “Being a mentor to Rachel was incredibly hard,” she said.

“I’ve always seen her as a soul singer, but she wanted to be a rock star, and as a result we’ve often disagreed.”

Last week Dannii upset Rachel when she named rival mentor Cheryl Cole’s act, Laura White, as her favourite to win the talent contest, prompting Simon Cowell to step in and mediate between them.

A source added: “Simon rapped Dannii for wasting Rachel’s talents with awful songs. He does realise she can be a handful and that Dannii has a difficult time trying to handle that.”
