Dannii MinogueDannii MinogueThere's been many a rumour of backstage bickering on The X Factor this year.

But when Sky Showbiz caught up with her, judge Dannii Minogue set the record straight.

When glam Dannii rocked up at the Music Industry Trust awards last night, to honour her big sis Kylie's win, the question on everyone's lips was:

What's really going on with The X Factor behind closed doors?

Gossip's been a-buzzing with talk of tension between the four X Factor judges - Louis Walsh, Sharon Osbourne, Simon Cowell and Dannii.

In particular there were rumours of backstage fisticuffs between Mrs O and Dannii, due to a simmering rivalry, some said.

But when we chatted to her, Dannii was at pains to emphasise that all judge-like competition was strictly above board.

"There's a healthy rivalry between us," Dannii told Sky Showbiz. "We're all desperate for our acts to win."

And who did she back to win?

"At the moment it could be any one of my three," she said modestly, referring to her three under-25 male acts - Leon Jackson, Andy Williams and Rhydian Roberts.

She added: "Cross fingers."
