LaToya Jackson claims her ex-husband told boxer Mike Tyson he could sleep with her for $100,000.

The 55-year-old star - who has previously accused Jack Gordon of attacking and threatening to kill her during their seven-year marriage - also insisted her spouse, who was also her manager, forced her to take part in group sex against her will and pose for Playboy magazine.

Speaking on US TV show 'The Talk', she said: "Mike Tyson later told my mother and father and some other friends that he [Gordon] had told him that if he wanted to sleep with me he has to pay $100,000.

"I was in brothels and everything ... [It was] everything I was against. He made me do Playboy twice and had me sit on the stage and say, 'Oh no, it was all my idea.' And I had to do that because I knew what he said he would do, he would do it."

La Toya claims she was forced into marrying Jack, who died in 2005, in 1989 and was too naive to realise what she was getting into.

Speaking about her new autobiography 'Starting Over', she said: "I wrote this book for women. It was very difficult for me, because when he [Gordon] took me, at that time I was a strict Jehovah's Witness and I knew nothing about the world whatsoever.

"I was 29 and one of those over the top religious people. I was mentally 16 because of not knowing the world and what people do, not everyone was honest and I believed everything they said."
