Outspoken reality TV judge Sharon Osbourne has launched an attack on Aussie actor Nicole Kidman, describing her forehead as “like a f***ing flatscreen TV”.

Osbourne, who is married to former Black Sabbath singer and ageing rockstar Ozzy Osbourne, slammed the “lying bitches” who won’t admit to having plastic surgery during an appearance on US talk show Chelsea Lately.

“Oh my God, those liars, I hate them, those bitches,” Osbourne said.

“They go, ‘Oh no, I wouldn’t do anything,’ meanwhile, there eyebrows are here.

“Nicole Kidman’s forehead looks like a f***ing flatscreen TV – how big is that forehead?”

While experts have labelled her an “enthusiastic user” of Botox, Kidman has always denied using the anti-wrinkle treatment.

“To be honest, I am completely natural. I have nothing in my face or anything,” she told US Marie Claire magazine recently.

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

Osbourne, who has freely admitted to having extensive plastic surgery, said stars should come clean about using Botox or going under the knife.

“If something bothers you, it doesn’t make you happy, then change it. What’s the deal?.

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