In a new interview with Hello! magazine, Ozzy Osbourne's wife, Sharon Osbourne, made the surprising revelation that she recently opted for a double mastectomy after doctors told her she carried a gene that put her at risk for breast cancer.

It was a relatively simple decision for Osbourne, who suffered through colon cancer 10 years ago. Describing it as "a no-brainer," she told the magazine, "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."

Also factoring into her decision: Experiencing the joy of being a first-time grandmother after Jack, Sharon's son with Ozzy, recently celebrated the birth of his first child with new bride Lisa Stelly. As Sharon put it, "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."

It's been a year full of health drama for the Osbourne clan -- earlier this year, the family publicly struggled with Jack's multiple sclerosis diagnosis. Here's hoping they manage to find a long period of relative normalcy after the extreme highs and lows of 2012.
