Marguerite "Rita" Duvall was a French dancer and actress, as well as Michael Corleone's girlfriend following his divorce with Kay Adams. She is also the mother of Fredo Corleone's only child, whom she gave up for adoption.
A French-born dancer in a "tasteful" Las Vegas nightclub, Rita Duvall once had a one-night stand with Johnny Fontane, who later asked her to offer her "services" to his friend Fredo Corleone. Their one-night stand resulted in the birth of his only child, whom Rita gave up for adoption, with Fredo's agreement. Prior to this, she had been girlfriend to the future President, James Shea.
By the 1960s, she had become a somewhat successful actress and Michael Corleone's girlfriend. She often attempted to bond somewhat with his children Anthony and Mary. The two eventually split some time before he received the Order of St. Sebastian, though it was an amicable parting.
