Vadim, the father of her daughter Vanessa, in 1967. She describes her ex-husband, who died in 2000, as 'cruel and misogynistic' and claims he forced her into other forms of group sex.
Rumours about the couple's sexual behaviour have been the subject of Hollywood speculation for years. Miss Fonda blames her relationship-with Vadim for the eating disorders that plagued her for much of her life.
'I ceased eating except for crusts from his bread and rinds from his camembert,' she says.
She believes Vadim's behaviour echoed that of her father, Henry Fonda, during her childhood.
Her mother, socialite Frances Seymour, had mental health problems and committed suicide when Miss Fonda was 12.
She grew up to become one of America's most controversial actresses.
She won two best actress Oscars, for Klute in 1971 and Coming Home in 1978.
But she became a national hate figure in the U.S. in 1972 when her opposition to the Vietnam War culminated in her posing with an enemy tank in Hanoi.
She divorced Vadim in 1973 and went on to marry twice more.
Her marriages to radical politician Tom Hayden in 1973 and CNN founder Ted Turner in 1991 both ended in divorce.
