In an explosive interview given to a tabloid paper, David Arden, Sharon Osbourne’s brother, claims Simon Cowell had her fired from X-Factor because she repeatedly told him he was gay.

“She tells everyone he’s gay. She claims he’s in the closet and doesn’t know yet he’s homosexual, which is ridiculous,” Mr Arden told the News of the World.

“Sharon told me that at the end of series one Simon actually got her fired for her jibes and nastiness to him and the contestants.”

Apparently, producers then convinced Mr Cowell to re-hire her because their chemistry was so effective.

Questions about Mr Cowell’s sexuality have refused to die down through his entertainment career, despite complaints from the Gay and Lesbian Alliance Against Defamation that some of his comments on American Idol turned a “contestant’s gender expression into the butt of a joke.”

But Arden’s claims do not stop there.

He also alleges Ms Osbourne defecated in Elton John’s driveway after being on the loosing end of a love triangle.

“Sharon and Elton both fancied the same young man in Los Angeles,” Arden claims.

“And when Elton was the one who finally got him into bed Sharon was furious.

“Accompanied by a friend of ours, who told me everything, she sneaked up to Elton’s Beverly Hills mansion, defecated on his driveway then used it for her own dirty protest all over his Rolls-Royce.

“It was absolutely appalling. But that’s just the way Sharon always retaliates.”

His sister is said to be livid at the publication of the article but is planning to correct any misapprehensions about her life with the publication of the second volume of her autobiography.
