Lorraine Bridges (August 17, 1906 – December 4, 1993) was an American actress and singer who was known for her ability to hit high notes. Bridges was a native of Oklahoma, where she was a singer for radio station WKY early in her career. Bridges was a contract player at Paramount; the studio dropped her in 1935. She was signed by MGM three weeks later. Bridges performed as a vocal stand-in, often uncredited, for actresses in popular films such as for BIllie Burke in The Wizard of Oz (1939) and Jeanette MacDonald in New Moon (1940), Bitter Sweet (1940), and Smiling Through (1941).
