Anastacia loves her "bionic boobies".
The 'I'm Outta Love' hitmaker underwent a double mastectomy last year after discovering she had breast cancer for a second time and she insists she "couldn't care less" about losing her natural breasts.
She said: "I call them my bionic boobies. They're fabulous. I was a triple D, now I'm a C-cup, so I'm perfectly happy.
"I can finally wear little spaghetti straps. Personally, I couldn't care less about losing my natural boobs. I wanted to be done with breast cancer."
The 45-year-old singer was insistent about having the operation, even though doctors said she didn't need to, as she didn't want to find herself battling the disease again in the future.
She told the Daily Mail newspaper: "This last time, it was such a small piece of cancer I could have had a biopsy and some treatment and called it a day, but I've been there. And that didn't change anything. It just came back.
"I thought, 'I don't want to go through this again. If I do, is there going to be a third time or a fourth? Will that be the killer?' I said to the doctor, 'I know this seems drastic to you because you'd like to keep my natural boobs, but I want to live. I don't want to play Russian roulette with my breasts and my life.' "
Anastacia insists she was "prepared" for the procedure as she had done her research several years before when she had another cancer scare.
She explained: "I was surprisingly prepared for it. Because about two years after the first diagnosis, I had an abnormal reading, so had to have a biopsy. I freaked out and researched a double mastectomy.
"The biopsy was benign and the recovery time from the operation was about a year, so I opted not to elect to do something, but it planted the seed, 'If it comes back, this is what I will do'.
"I had many years to sit with that."

Michael Jackson's ex-wife wants guardianship of their children.
Debbie Rowe - who was married to the late 'Thriller' star for just under three years until October 1999 and had children Prince, 17, and Paris, 15, with him - is also said to wants to take responsibility for Michael's son Blanket, 12, who was reportedly born via surrogate.
According to TMZ, Debbie thinks their grandmother Katherine Jackson, who is the children's legal guardian, is too old to care for them properly.
A source said: "Debbie is deeply concerned about the environment in the Jackson home. She likes Katherine Jackson but believes she has gotten way too old to serve as guardian."
She reportedly told a friend: "Katherine's not connected with the kids or involved in their lives."
Debbie, 55, is also said to be concerned Michael's brothers are spending too much time at their Calabasas house in California and have been a "terrible influence" on the children.
She is also rumoured to be "upset" with Michael's brother Jermaine, who will appear on 'Celebrity Wife Swap' in coming weeks, because she thinks it's "extremely inappropriate".
Debbie is set to file legal documents asking the judge to appoint her guardian so she can move the children to her ranch in Palmdale, California, where she has a business raising and breeding horses.
She originally lost contact with her children after divorcing Michael in 1999, but has been getting closer to them over the last year with the blessing of the Jackson family.
