Sharon Osbourne has admitted that walking off the X Factor last Saturday was a big mistake.

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 took pity

“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?”
