Outspoken reality television personality Sharon Osbourne has launched a scathing attack on Oscar-winning actress Nicole Kidman after claiming that the Australia-born star is lying about having plastic surgery.

Nicole has always denied using the anti-wrinkle treatment Botox.

“To be honest, I am completely natural. I have nothing in my face or anything,” she told Marie Claire Magazine last month.

“I wear sunscreen, and I don’t smoke. I take care of myself and I’m very proud to say that.”

“Oh my God, those liars, I hate them, those bitches,” the wife of Black Sabbath rocker Ozzy Osbourne said during a recent appearance on E!’s Chelsea Lately.

“They go, ‘Oh no, I wouldn’t do anything,’ meanwhile, they’re eyebrows are here,” Sharon added.

“Nicole Kidman’s forehead looks like a fucking flatscreen TV - how big is that forehead?”

“If something bothers you, it doesn’t make you happy, then change it. What’s the deal?,” says Sharon, who has been candid about her extensive cosmetic surgeries.

“I don’t get what the mystique is, why people lie about it.”
