Dannii Minogue has defended herself over her feud with Sharon Osbourne – saying the former X Factor judge is not welcome in her “dressing room”.

Dannii, who makes her X Factor comeback on Saturday after a spell on maternity leave, defended herself after being called a liar and “the devil” by Sharon’s daughter Kelly on Twitter.

Asked whether she had been upset by the tweets, Dannii, 38, told X Magazine: “I just put what happened in the book. I don’t want to get into the back and forth of this. (I’m) not really angry. I laughed. I know what’s true.

“They’re strong accusations. I’m not a liar – if she’s calling me a liar, she’s calling everyone who was there a liar. The producers and everyone. There were a lot of witnesses.”

Dannii made the comments as 57-year-old Sharon prepares to return to the X Factor – to the judges’ houses stage of the competition.

The Australian said: “It’s not awkward, it’s separate things and we have no contact. It’ll be interesting to see how the fans react to her.”

She added: “She’s welcome any time (to the show). Just not in my dressing room.”

The star wrote in her autobiography that Sharon stormed into her dressing room and launched a tirade of abuse at her with just minutes to go before they went on air when they were both judges on the show.

Kelly Osbourne then took to Twitter to say: “I will be the first one to admit that my mother did not play her cards right when it came to Dannii but trust me when I say Dannii is the devil.”
