In a recent interview with Howard Stern, Sharon Osbourne revealed that she and her husband Ozzy Osbourne underwent expensive DNA screenings to ensure that they were both in good health.

Sharon, who battled colon cancer in 2002, said it was a big cost, but ultimately necessary.

"It was hugely expensive -- $250,000," the television personality shared via UK's The Daily Mail. "The scientists wanted to see how Ozzy had lived so long despite the drink and drugs. I said he would do it and they said, 'We are doing you, too,' The tests tell you all your genes and what you might get or have got."

Sharon said the results were shocking. "My husband walks away and he is genetically blessed and is perfect, thank God," she said. "But I had colon, breast and ovarian cancer genes."

It was then that Sharon decided to have a double mastectomy. "I had my entire breasts cut off and they rebuilt them," she said. "They look very small and perky, like they belong on somebody else but me. I have only got one nipple but I am going to have the other done ... I am so busy and now it looks like my tits wink at my husband every morning."

Regardless to adjusting to her new breasts, Sharon says she just feels lucky to be healthy and alive. "When you're my age it is not that I don't care, it's that I am past all that," she explained. "I love being glamorous and looking the part, but it is not the be all and end all."

In a previous interview with Hello! Magazine, she said of the double mastectomy, "'For me, it wasn't a big decision, it was a no-brainer. I didn't want to live the rest of my life with that shadow hanging over me ... I want to be around for a long time and be a grandmother to Pearl. I didn't even think of my breasts in a nostalgic way, I just wanted to be able to live my life without that fear all the time."
