Born in Sioux City, Iowa, on January 18, 1920, she was raised in Dallas, Texas, and nurtured ambitions to be a singer. The one-time brunette with the rich contralto started out as a band vocalist prior to entering films. Universal took notice and signed her up initially, but she is probably better known for the vocal work she did as leading lady in Republic Pictures tunefests, her best showcases being Show Business (1944) and Atlantic City (1944). In the former, she joined co-stars Eddie Cantor, George Murphy and Joan Davis in the vintage songs "I Want a Girl, Just Like the Girl That Married Dear Old Dad" and "Dinah". In the latter, she was top-billed and soloed on "After You've Gone" and "On a Sunday Afternoon".
She also occasionally worked up elegant nightclub acts. Married in 1939 to agent John Maschino and the mother of two, her husband later became a successful real estate agent. After her retirement, Constance indulged herself in still life painting. Her husband passed away in 1998 and she followed in 2005 of heart failure following a long illness. The couple had two children.
