The woman who claims to have inspired the film Manhattan is speaking out about her relationship with Woody Allen.

Babi Christina Engelhardt tells The Hollywood Reporter that she was a 16-year-old high school student when she began dating a 41-year-old Allen, saying that she actually made the first move by giving the director her number.

They were together for eight years she says, and around the time she was 20 the twice-divorced Allen introduced her to his new girlfriend, Mia Farrow.

Soon after, according to Engelhardt, she began having threesomes with Allen and Farrow.

Engelhardt says she enjoyed Farrow's company and the two would smoke joints and discuss astrology and animals, with the former model seeing Allen's new girlfriend as a victim.

'I felt sorry for Mia,' Engelhardt says, making reference to the fact that Allen would eventually go on to betray her by having an affair and then marrying her adopted daughter Soon-Yi Previn.

'I thought, "Didn't Woody have enough 'extra,' with or without her, that the last thing he had to do was to go for something that was totally hers?"'

She then adds: 'He had groomed Mia, trained her, to put up with all of this. Now he had no barriers. It was total disrespect.'

Shocking claims: Babi Christina Engelhardt (above in 2006) was with Woody Allen for eight years, and began seeing the director when she was a 16-year-old high school student

Groupo: Halfway through their time together the pair allegedly began having threesomes, and according to Engelhardt a 'handful' of these were with Mia Farrow (Farrow and Allen in 1983, around the time the threesomes stopped between the pair)

Teen queen: Engelhardt says she was hesitant at first to be intimate with a woman but grew to like Farrow as they smoked weed and talked about astrology during the trysts (the former model in 1977 at the age of 17)

Engelhardt claims she had group sex with other young women that Allen brought in before being introduced to Farrow.

She also explains that she was resistant about being intimate with women, but grew fond of Farrow.

'There were times the three of us were together, and it was actually great fun. We enjoyed each other when we were in the moment. She was beautiful and sweet, he was charming and alluring, and I was sexy and becoming more and more sophisticated in this game,' recalls Engelhardt of the time.

'It wasn't until after it was done when I really had time to think of how twisted it was when we were together … and how I was little more than a plaything.'

She adds: 'While we were together, the whole thing was a game that was being operated solely by Woody so we never quite knew where we stood.'

Allen and Farrow both declined to comment.

At first, Engelhardt says she was upset to be meeting Allen's girlfriend since she was under the impression that she was in a relationship with the director.

'I felt sick. I didn't want to be there at all, and yet I couldn't find the courage to get up and leave. To leave would mean an end to all of this,' she writes in a manuscript for her memoir, which she shared for the first time.

'Looking back now, that's exactly what I needed, but back then, the idea of not having Woody in my life at all terrified me.

'So I sat there, patiently, calmly trying to assess the situation, trying to understand why he wanted the two of us to meet.'

'I used to think this was a form of mother-father with the two of them,' says Engelhardt (at 17 above)

The relationship also took on another surprising element according to Engelhardt.

'I used to think this was a form of mother-father with the two of them,' she says of her time with Allen and Farrow.

'To me, that whole relationship was very Freudian: how I admired them, how he'd already broken me in, how I let that be all right.'

Engelhardt also reveals that the only time she ever saw Allen show emotion was the day he received some devastating news from another ex, Diane Keaton.

'It caught him off-guard,' she recalls of the phone call from the Annie Hall star telling him the cat they used to share had died.

'He just sat there next to me and looked at his hands. They were trembling. In that moment he wasn't even in the room.'

Allen was so aloof and disinterested in helping Engelhardt with her own career that he did not even realize that she booked work on his film Stardust Memories.

'My dream was that he'd have seen me and pulled me out from the crowd,' she said of her day working as an extra on the set of the 1979 film.

'But I showed up with the crowd and left with the crowd.'

Her relationship with Allen was confirmed by her brother and the photographer she was with on the night she gave the filmmaker her number.

She also shared a letter she received from the director recalling their relationship fondly and asking her to meet his new wife in 2001 after she sent him a documentary on Federico Fellini.

Engelhardt became a platonic muse for the Italian filmmaker after leaving Allen.

As for her claim that she was the inspiration for Manhattan, it would be more likely the character was a composite of the model and actress Stacey Nelkin, who Allen started dating when she was 17 and still in high school.

Hemingway, who was later nominated for an Oscar for her work in the film, was 16 when she was cast in the project.

Farrow would later end her relationship with Allen in 1992 when she found nude photos he had taken of her adopted daughter Soon-Yi Previn.

In an interview earlier this year, Previn said that what Farrow then did began the narrative that has lasted for almost three decades.

Previn was then kicked out of the house but then let back in, though she believes that she was being followed by an private eye hired by Farrow.

Previn's relationship with Allen continued in secret, while Farrow sent Allen a 'gothic' Valentine a month later that showed he heart with a knife through it and their children on skewers.

Farrow and Allen were also still working together on what would be their final film together, Husbands and Wives.

Previn and Allen stayed in touch when she went to work at a camp that summer, and by August she had been kicked out for talking on the phone too much with a 'Mr. Simon.'

Farrow seems to have discovered the two did not separate on August 1, when she reportedly called psychologist Susan Coates and said that she needed to 'find a way to stop' her 'satanic and evil' ex.

Three days later, Farrow's adopted daughter Dylan Farrow was allegedly abused by her father in an attic crawl space.

It was a week later that Allen claims Farrow's lawyers offered him a confidential settlement agreement that would have buried the allegations for $5 to $7 million.

He responded by suing Farrow in court for custody of Ronan as well as Moses and Dylan.

Allen had an uphill battle as in addition to the abuse claims he had only became the father of Dylan and Moses in December 1991, just a few months prior and right around the first time he admitted to having sexual relations with Previn.

Farrow had agreed to the adoption at Allen's insistence with the director asking her to allow him that role because she wanted to take in another child.

On August 17, Allen issued a statement in which he very publicly declared his love for Previn, the first time either had used the word.

'I only knew that he loved me when he gave the press conference and said it publicly. Even then, I wasn’t sure if he meant it. We had never said those words to each other,' said Previn.

A team of three investigators from Yale–New Haven Hospital came to the conclusion that Dylan had been coached by Mia in 1993, but the judge still ruled against giving Allen custody.

The director also lost his appeal, despite New York State child-welfare investigators finding no evidence of any misconduct on Allen's behalf in a second probe into the allegations.

In 1997 Allen and Previn married in Venice, and a few years later adopted two daughters: Bechet, 19, and Manzie, 18.
