Glenn Miller discovered her in London, and she sang for the Army Air Force Orchestra. She moved to Los Angeles after the war with her father's big band, and with Frank Sinatra for one year on Your Hit Parade.
She was part of The Four Girls singing group, with Jane Russell, Rhonda Fleming, and Connie Haines. They recorded sixteen singles, and albums which became best sellers. She appeared both in variety shows and films.
In 1996, a Golden Palm Star on the Palm Springs, California, Palm Springs Walk of Stars was dedicated to her.
