Kelly, 30, revealed about the same while discussing Jolie's recent admission that she had her ovaries and fallopian tubes removed after her doctor found inflammatory markers in her blood test which could be a sign of early ovarian cancer, reported Us magazine.
"I actually do have the cancer gene," she said on her mother Sharon Osbourne's talk show.
"My mom made all of us get tested after she found out that she had it and got her double mastectomy. I know that one day I will eventually have to do it too because if I have children, I want to be there to bring them up. I want to be there to support them in every way I can," she added.
