The "Believe" singer, 72, has made it known that her biggest wish is to preserve her body after she dies.
"She has recently become obsessed with researching cryonics," a source close to the singer told RadarOnline.com. "She figures she's worked so hard with both doctors and sticking to a healthy lifestyle to look decades younger than she is, why not continue that when she's gone?"
According to a source, Cher was "shattered" at the time, and friends worried her grief would trigger a relapse of the deadly virus.
After undergoing some cutting-edge treatments in Germany, she is now focused on looking flawless even in death.
"Everyone's pretty horrified by it and laughs it off, saying she's got a few years left in her yet to decide for sure, but she's determined," the source said.
