Hollywood legend Jane Fonda confesses in her forthcoming autobiography that her former husband Roger Vadim forced her her to invite other women to their bed and participate in threesomes.

In her book, My Life So Far, which is due in April, the 67-year-old silver screen siren describes the French director as «cruel and misogynistic» and writes how he encouraged her to use the techniques she learned from her performance as a prostitute in the 1971 movie Klute to chat up women.

The Barbarella star, who became an icon of female sexual liberation, says Vadim once even ordered a red-haired prostitute from an escort agency in France to join the couple and fulfill his sexual fantasy.

Fonda admits she agreed to the group sex because Vadim, who was previously married to Brigitte Bardot, manipulated her by making her feel "less than perfect".

"It seems shocking that I did that but I convinced myself that it was fine even though it was killing my heart," wrote the Oscar-winning actress, according to Mirror.co.uk.

However, as reports Contactmusic.com, Jane Fonda's publicists are denying such claims published by the British tabloid.

In a statement released yesterday, the actress' spokesman says, "This did not come from the manuscript. There are major inaccuracies, as people will see when they read the book."

The famous couple were married from 1967 to 1973 and had one daughter. Roger Vadim died of cancer in a Paris hospital in 2000.
