Dannii hits back in Osbourne feud

Dannii Minogue has hit back over her feud with Sharon Osbourne -- saying the former X Factor judge is not welcome in her dressing room.

Minogue, 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 Osbourne's daughter Kelly on Twitter.

Asked whether she had been upset by the tweets, Minogue (38) told X Magazine: "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. The thing is, it's not a big part of the book. It's just all everyone's read from it right now."

Minogue made the comments as Osbourne (57) prepares to return to the X Factor for the judges' houses stage of the competition to help Louis Walsh pick his finalists.

The Australian added: "She's welcome any time (to the show). Just not in my dressing room."

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