The mother-of-two has been extremely candid about the toll having a double mastectomy took on her body and her mind. "All I care about is that I'm alive and I'm here for my baby. But putting that to the side, I'm like, one day people will forget or not know that I had cancer, but they'll look at me and go, 'Oh, what a bad b--- job,'" she admitted during a recent episode of the "SHE MD" podcast.

When she looked at her body after she said she "was by myself in my bathroom, and I looked at them and I cried in a way that I don't think I've ever cried in my life. I was devastated. I didn't recognize myself."
