Sharon Osbourne once spent a staggering $2 million for a ring.

Speaking to The Sun newspaper, she said: "The most I ever spent on myself was probably a ring I bought about 12 years ago for about $2 million. I bought the ring from Tiffany's."

It's no surprise that Sharon likes to treat herself as she has to work with Simon Cowell, and be the head of her busy family which includes husband Ozzy Osbourne - who she recently reconciled with following his treatment for sex addiction - son Jack Osbourne and daughters Aimee and Kelly Osbourne.

The family previously starred in their own MTV reality show 'The Osbournes' which documented their home life and recently Sharon has been thinking about a Hollywood movie about her clan.

She said: "If there was a movie about the Osbournes I would be played by Meryl Streep. If she could play Margaret Thatcher then she could do me! I reckon the Osbournes' life would make a fantastic film."

Sharon, 63, and Black Sabbath rocker Ozzy, 67, are putting their marital troubles behind them and working hard to get their relationship back on track following his multiple infidelities.

Speaking previously, Sharon said: "He's working at it (his sex addiction). It's hard because it affects the whole family. And, it's quite embarrassing to talk about.

"Somehow drugs and drink is more acceptable I think. When it's somebody that has a sex addiction, it's embarrassing.

"He's come out and admitted it finally. It's very, very hard. It's been going on for at least six years."
