“I’m empowered… I’ve found an inner strength,” Sharon Osbourne told her co-hosts on yesterday’s episode of CBS' The Talk. Sharon rejoined her co-hosts after taking Monday off amidst a media storm over trouble in her 33-year marriage to Ozzy.

Asked on The Talk if it was true that she had kicked Ozzy out, or just a rumour, Sharon bluntly replied, “No, it’s true!” On whether or not he was still out of the house, Sharon updated by saying, “No, he’s back, and I’m out of the house.”

Speaking calmly of her turmoil, Sharon added: “I honestly, at this point today, have no idea what I’m going to be doing with the rest of my life. I need time to think. I really want to think about it very carefully.”

Having gone through problems with Ozzy throughout their marriage, Sharon was asked if things were different this time, to which she replied, “I’m 63 years of age and I can’t keep living like this.”

Has she talked with Ozzy since this all went down? “I spoke to him last night,” she said. “I’m not with him, but I speak with him.”

Sharon continued: “I love Ozzy dearly, he’s given me an unbelievable life and three gorgeous children.”

Asked if she thought that her and Ozzy would break up for good, Sharon said, “At this point I can’t answer that.. I don’t know what I want.”

On May 9th, Ozzy spoke to E! News after word broke that the Prince of Darkness and his wife are splitting. With many reports circulating about the break up, the Black Sabbath vocalist wanted to end one rumour immediately. "I have been sober for three and a quarter years. I have not touched drugs or alcohol in that time. Any reports that I am not sober are completely inaccurate."

Ozzy will be on stage with Black Sabbath at their upcoming farewell shows. When this tour concludes, it will truly be The End, The End of one of most legendary bands in rock 'n roll history... Black Sabbath.
