Barbara Mensah wants a six-figure sum for the footage which shows the legendary fighter at special post-fight get-together.
The 70-year-old claims ?no one has anything like this?.
She was entrusted with the footage by one of Ali’s entourage before his death.
She added: ?I know the value of the footage. I?d like to get as much as I can get for it.?
Talking about the footage, Barbara said: ?There would be Ali and a few of his guys and then about a dozen or more girls.
?All of them were stunning. Muhammad couldn?t keep away from a pretty girl whether he was married or not.
?The tapes show them having sex.
?They used to call them gumbo parties ? it was a mix of everything,? she said in an interview with The Sunday People.
She claims to have also written a ?blockbuster? book about her life with Ali.
Although Ali is not named on the birth certificate, Barbara claims she and the boxer had a child together.
Now aged 35, Kiiursti looks remarkably like the ex-world heavyweight champ.
Barbara claims a paternity test in 1988 proves Kiiursti was his child.
Barbara was in Louisville, Kentucky, for a Muslim prayer service for Ali on Thursday.
He was buried at a funeral on Friday.
She wrote on Facebook: ?It really, really hurts and only time will ease the pain R.I.P until we meet again.
?I?m so glad I came to say goodbye to my love you were always there for me I never would have miss your home going for the world.?
