X Factor judge Dannii Minogue has planned her revenge on rival Sharon Osbourne and plans to hit back at her in her new autobiography.

Sharon Osbourne has never made any secret of her hate for her one time X Factor colleague and in an interview with The Guardian last year she said:

“Dannii – I couldn’t stand her. She wasn’t so much a dim bulb as a bulb in a power cut. F**king useless.”

During an appearance on Piers Morgan’s Life Stories Sharon said that Minogue had “no sense of humour” and “bad plastic surgery” adding:

I didn’t hate her because hatred is very close to love and takes a lot of emotion and I don’t have that time for her” she said “she was like an insect, a mosquito that wouldn’t go away.

So now it’s Dannii’s turn to hit back and when asked about her new autobiography and whether her X Factor colleagues would have to worry about its contents, she told The Sun:

“They won’t – but Sharon might!”

A source added:

Dannii’s got the chance to tell the world exactly what she thinks of Sharon.

“She’s not going to hold back considering the abuse she’s received.

“They haven’t spoken for ages and Sharon hasn’t been in touch to congratulate Dannii on her pregnancy. There’s certainly no love lost between them.”
