Osbourne: 'Walking out was a mistake'

Sharon Osbourne has admitted that she made a big mistake by walking out of The X Factor on Saturday night, and has revealed that she has not been asked back by ITV.

The TV show judge declared "I'm out - gone!" live on the programme after two out of three of her acts were in the bottom two and she was called upon to help choose which one to send home.

Osbourne, who reportedly argued with co-judge Dannii Minogue before the show, has now admitted that she was wrong to storm off.

During an interview on Paul O'Grady's Channel 4 show, she explained: "I had just had it up to here. I thought 'I'm not going to take anymore'.

"I have made mistakes. I made one on Saturday ... I can't apologise for being me.

"I don't know if ITV want me back. I want to go back to take care of my girls but I've not heard from anyone. I'll pay for the call."

O'Grady then made a plea for Osbourne to be allowed back on the X Factor, saying: "You've got to go back or there's no show. You're the cog in the show.

"If you're watching can anyone do the courtesy of picking up the telephone?"
