July 27 (UPI) -- Singer Carly Simon, 83, announced Monday that she has been living with Parkinson's disease and underwent surgery for basal cell carcinoma.

The singer said she was diagnosed with Parkinson's after she had knee and hip replacement surgery for arthritis.

In a statement, the "You're So Vain" and "Nobody Does It Better" singer said, "Between my mobility issues, the Parkinson's diagnosis, the surgery, and the emotional effects of it all, withdrawing from public view was the most palatable reaction. If a person is allowed to hibernate during both winter and summer, then I have become an all-season bear. But I have not stopped living, and I have not stopped working."

Simon said she is working on a new album, "Comes in Waves," her first since 2008.
