Bo Derek (/ˈdɛrək/; born Mary Cathleen Collins; November 20, 1956) is an American film and television actress, movie producer, and model perhaps best known for her breakthrough role in the 1979 film 10. The film also launched a bestselling poster for Derek in a swimsuit, and subsequently she became one of the most popular sex symbols of the 1980s. She was directed by husband John Derek in Tarzan, the Ape Man (1981), Bolero (1984) and Ghosts Can't Do It (1989), all of which received negative reviews. A widow since 1998, she lives with actor John Corbett. Now in semi-retirement, she makes occasional film, television, and documentary appearances.
Derek was born Mary Cathleen Collins in Long Beach, California. Her father, Paul Collins, was a Hobie Cat executive, and her mother, Norma, was a make-up artist and hairdresser to Ann-Margret. Collins' parents divorced, and her mother married American stunt performer Bobby Bass.
