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.''
