SHARON OSBOURNE’ stunning confession – she underwent a double mastectomy.

She endured the ordeal after learning that a gene she carries put her at serious risk of breast cancer.

"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," the former America’s Got Talent  judge said in a sitdown with Hello magazine.

The 60-year-old show biz personality said "the odds" would not be in her favor if she didn't go through with the procedure.

"It's a decision I made that's got rid of this weight that I was carrying around," Sharon said.

Sharon, who battled colon cancer more than 10 years ago, said, "I’ve had cancer before and I didn’t want to live under that cloud: I decided to just take everything off, and had a double mastectomy."

"I didn’t even think of my breasts in a nostalgic way," Sharon said, "I just wanted to be able to live my life without that fear all the time."

Sharon's son Jack is battling MS, reported.
