Sharon Osbourne has said that she left 'The X Factor' because of Dannii Minogue.

In an interview with Closer magazine, Osbourne said: "I left because of Dannii Minogue. Simple as that."

She continued: "I didn't enjoy working with her at all and didn't fancy the prospect of spending six months sitting next to her."

Osbourne rejected the claim that her poor relationship with Minogue was due to jealousy of the younger woman's looks.

"I've not built my career on my looks or my youth," said Osbourne.

"There was no competition in that way."
