Sharon Osbourne found working with Dannii Minogue ''deeply irritating'' when the star was having a fling with Simon Cowell as she became overbearing and acted inappropriately ''sticking her tongue in Simon's ear'' on the set of 'The X Factor'.
The 60-year-old TV personality found it difficult to work with the 41-year-old brunette beauty during her time on 'The X Factor' UK panel in 2007 because she flaunted her relationship with the boss on set.
She said: ''She [Dannii] clearly felt s***ging Simon gave her vicarious power and it was so immature, not to mention deeply irritating to deal with.''
Sharon alleges Dannii became bossy and overbearing and acted inappropriately behind the scenes doing things like ''sticking her tongue in Simon's ear'', which made Sharon and fellow judge Louis Walsh feel uncomfortable.
In her autobiography, 'Unbreakable', Sharon wrote: ''The closer she got to Simon, the more I felt she started telling the producers what to do. Suddenly, from being the new girl, she was saying, 'This isn't right,' and, 'Simon doesn't like it this way.'
''Meanwhile the antics behind the screen had gone up a gear, with her sticking her tongue in Simon's ear and giggling like a bloody teenager as Louis Walsh and me stood there like a couple of gooseberries.
''For me, it made her so unbearable to work with that I just couldn't take it. It was horrible. My stomach was constantly knotted with anxiety about it and as each show loomed I would wake up and think,
'Oh God, I have to spend the day sitting alongside her again. ' ''
After an unsuccessful meeting with the executive producer Richard Holloway which didn't help resolve differences between Sharon and Dannii she turned to media mogul Simon asking him to choose which girl he wanted to keep but he was not willing to pick.
Sharon explained: ''I was here to fight my corner ... I walked in, gave him a kiss on each cheek and launched straight in. 'I can't take it anymore. It's her or me,' I said.
''His expression remained impassive. Simon is used to spats between the women in his life and clearly takes it all in his stride. 'I'm not going to make that choice, Sharon. I'd like you both to stay.' ''
Meanwhile, Simon - who is a judge on 'The X Factor' USA - is expecting his first child with girlfriend Lauren Silverman.
The Californian rockers were defiant in their intention to play the venue once again.
