At one point in the book, according to The New York Daily News, Parker recalls MacLaine pressuring her into losing her virginity to her boyfriend while a pair of sex therapists were staying at their house. Parker writes that she felt "like Mia Farrow surrounded by Satanists in Rosemary's Baby."Afterward, the therapists were eagerly waiting with questions. "Did you achieve climax?" they asked, according to Parker. "We both nodded vigorously. They smiled smugly. I hated them," Parker wrote.MacLaine denies much of the book, telling Peoplethat it's "virtually all fiction." "I'm sorry to see such a dishonest, opportunistic effort from my daughter," MacLaine said.

But Parker is standing by her story and will share more on Friday's episode of 20/20. "She was very absent," Parker said of MacLaine's parenting. "I was very lonely — very lonely. Definitely. And I still struggle with abandonment issues and loneliness." According to Parker, MacLaine could only handle playing mom for only four hours at a time. After that, Parker says she became a burden.At 2 years old, MacLaine shipped Parker off to Japan to live with her father. And since the actress didn't accompany her toddler, Parker says the stewardesses acted as her caregivers.MacLaine, 78, rarely saw her daughter and was "very old-school regarding money and tough love," Parker said. Since her mother refused to help, Parker said she was unable to afford college and had to work as a maid, waitress and stewardess.

When MacLaine began writing New Age books, she reportedly told her daughter that the man she was living with wasn't her father, but was actually a clone. She said Parker's real father "Paul" was actually orbiting in space, something MacLaine paid $60,000 per month to purportedly keep up, according to Parker.Though the book is damaging to the beloved actress' image, Parker, 56, hopes her mother "see[s] the positive" in it, even sending her a copy with a note saying "I love you.""I did everything I could to bring Mom into my life. The Hollywood ending never happened," Parker wrote. "Now that I've written this book, it probably never will."20/20: Stars, Scars and Showbiz Kids airs Friday at 10/9c on ABC.
