Dannii Minogue fell out with Louis Walsh big style after his rather cruel jibes about her singing talent.

But it's not the first fallout to rock the reality show. We remember the best rows ever...

Watergate
During the second series of the X Factor, judge Louis Walsh got a soaking he never predicted after pushing Sharon Osbourne's buttons. Asking Sharon if she'd been taking husband Ozzy's medication after a bout of hysterical laughing from the female judge, the Irish pop lover soon got his just deserts when Sharon threw a glass of water in his face. Simon, for once pleased to not be involved in the rows, could only sit and laugh.

Louis's exit
Louis had enough of Simon's put downs during the same series and, after becoming the audience's least favourite judge, declared he was quitting the show. "I've had enough. I'm going back to Dublin. I'm not putting up with it any more. I have been totally humiliated and undermined by both of them", Louis said at the time, while his act Shayne Ward was left in limbo. Only Simon could talk him back into returning, promising to be nice.

Blonde ambition
Sharon was raging again when Simon and Louis lumbered her with the job of telling hopeful band Eskimo Blonde that they hadn't made the cut in auditions for series three. Louis and Simon both quit the audition room after making their own decisions, leaving an emotional Sharon to let them down. Once she'd dismissed the band, she turned on her panel "buddies". "You are both taking the p*** out of me and it's not fair. I wouldn't do that to you, I would support you", Sharon spat at the giggling pair, backstage.

Sharon vs Dannii
The most famous of this year's spats involved female judges Sharon Osbourne and Dannii Minogue. Rumoured to hate each other, the pair reportedly row backstage before putting on a front for each show. Dannii has recently admitted that they don't "click".

Louis's axe
Even before this series began, there were cross words. Simon famously axed judge Louis Walsh from the show, leaving him fuming. Louis ranted to the papers how poorly he'd been treated, before Simon surprised everyone and called for his reinstatement just weeks into filming the fourth series.

Kimberley's exit
Sharon "quit" the series after the first live show this year, when her act Kimberley Southwick was voted off. Claiming that she'd had enough, the temperamental judge flounced off the set, snubbing ITV2 show The Xtra Factor. She was coaxed back by Simon Cowell in time for the next show.
