School, Reseda, California. Adult career At age 18, Cupito changed her name to Morgan Brittany and then appeared with Gene Kelly in his Las Vegas show, Gene Kelly's Wonderful World of Girls, as a dancer. She then moved to New York City, where she modeled for the Ford Modeling Agency, and appeared in several TV commercials and print ads (including a three-year stint as "The Ultra Brite Toothpaste Girl"), and was spokesmodel for brands such as L'Oreal, Maybelline, Ford, Levi's and Camay. In December 1972, she played Cynthia, a childhood friend of Bridget's (Meredith Baxter), in episode 12, "The Homecoming" on Bridget Loves Bernie. In 1974, she was hired by the Japanese cosmetics company Kanebo to be the "face" of their product "Ireine", and so moved to Tokyo from 1974 to 1976 and traveled around the world as the image of "Kanebo Cosmetics". Brittany portrayed actress Vivien Leigh in Gable and Lombard (1976) a biography of Clark Gable and Carole Lombard. She also had a cameo appearance in the John Schlesinger film The Day of the Locust (1975) as Leigh in the climax of the film.

In 1980, while filming an episode of The Dukes of Hazzard, Brittany met her future husband, stuntman Jack Gill. She appeared again as Vivien Leigh in the climax of the made-for-TV movie about the search for an actress to star in Gone with the Wind's film adaptation, The Scarlett O'Hara War (1980), which marked the second of her three portrayals of the British actress.

She debuted on Dallas in the 1981–82 season and her role as Katherine continued, on and off, until 1987. In 1985, she returned for a cameo in that season's finale where her character killed Bobby Ewing by running him over with a car, killing herself in the process.
