In her new memoir, model-actress Brooke Shields describes her complicated relationship with her late mother-manager, and details her celebrity-filled life while growing up.

In excepts from "There Was a Little Girl: The Real Story of My Mother and Me" posted Wednesday at People magazine's website, Shields says her alcoholic stage mother, Teri, would often leave Brooke with a neighbor in order to go out drinking at night. Teri Shields thrust her child into modeling at 11 months and micromanaged the young woman's career to the point of insisting Brooke's teenage memoir include a chapter on her virginity.

"I was her greatest creation," Shields, 49, writes in the new book, being published by Dutton Adult on Tuesday. "It was us against the world."

Yet she concedes that, "Even though I understood her better than anybody else, I'm not sure I ever understood her fully."

The memoir, a follow-up to 2005's "Down Came the Rain: My Journey Through Postpartum Depression," also discusses Shields' romances. The author writes of going on a date with John F. Kennedy Jr. after the late president's son gave her a tour of Brown University, which Shields had considered attending, and of being proposed to by actor Liam Neeson, albeit without a ring. She relates her "definitely one-sided" crush on singer George Michael, who did not come out as gay until 1998, and her platonic love of Michael Jackson, whom she met when she was 13.

It was while attending Princeton University that she lost her virginity, at age 22, to her classmate and boyfriend, the future actor Dean Cain ("Lois & Clark: The New Adventures of Superman"). "He was incredibly and painfully patient with me regarding sex," Shields writes. "I made him wait and wait and my mom kept track."
