Cher was "traumatised" that she`d never hear her daughter`s voice again
The 64-year-old singer begged her son Chaz Bono - who was born a female named Chastity and began gender reassignment surgery around three years ago - for a copy of his old female answering machine message after becoming "hysterical" when she called and reached his new voicemail.
She said: "I was hysterical one day because I was calling Chaz`s answering machine and I realized it was her old voice, and then I said, `Chaz is there a way I can save it because I will never hear that voice again?` And there wasn`t, it was gone.
"That`s the most traumatic thing that has happened to me in this whole thing - hearing her voice and knowing I`ll never hear it again.
The `Believe` hitmaker also admitted she avoided seeing Chaz - whose father in the singer`s late husband Sonny Bono - for a long time after he began treatment because she was so nervous.
She admitted in new documentary `Becoming Chaz`, she said: "I was so nervous. I hadn`t seen her and I was putting it off.
"My boyfriend finally said, `This is crazy, just do it.` I said, `I`m so terrified of what will happen. If I don`t recognize her, what will happen?"
Cher also admitted she still doesn`t feel "comfortable" referring to her offspring as "him" rather than "her".
She added: "At some point, I`m gonna have to start calling her `him`. It doesn`t seem comfortable to me yet. Actually I just can`t remember and I guess I`ll start forcing myself but I`m not sure she cares."
