Sharon Osbourne Sharon Osbourne When Sharon Osbourne left The X Factor, we were reeling from the shock.

And although it's all over now and Cheryl Cole's stepped into her shoes...

We were never exactly clear on why Shazza left the show.

But now an X Factor insider has stepped forward, and says he knows the answer.

Executive producer Richard Holloway told The Sun: "I think her demands were unreasonable. From a financial point of view, it was absolutely right to say there was no more money."

According to the paper, Sharon was reportedly on a salary of £1.5m and was apparently holding out on a salary rise of £500,000.

"Sharon didn't want to do the next series," Richard added. "We wanted her to stay on, without question, but it was totally and utterly her choice."
