Born in Tekoa, Washington, Bailey sang with Paul Whiteman and his Orchestra from 1931 to 1933. In the mid- to late 1930s she made many recordings with her husband Red Norvo and his Orchestra. Mildred married Red in 1933, and they divorced in 1945. She died in Poughkeepsie, New York of heart failure chiefly due to her diabetes.
