All's well that ends not so well. Mary-Louise Parker's personal life took center stage in the media in the early 2000s when her then boyfriend Billy Crudup left her for Claire Danes. Mary was seven-months pregnant at the time with Billy's baby.

In an interview on "Today" about her new memoir, "Dear Mr. You," the "Weeds" actress spoke about that devastating time in her life, all without mentioning her baby's daddy by name. She only said that it was "personal," but also a "very low moment" in her life.

"I wanted to write something that was positive," she told Savannah Guthrie. "To me, it was a bunch of thank you notes. My ruminations on the gender itself, and my love of things male and men in general ... I've had amazing heroic men in my life starting with my father and my brother."

She also has another amazing man in her life, her 11-year-old William who she was carrying when Billy left her. "It was something that I had waited for all my life," she said of motherhood. "I wanted a baby my whole life. I was a little girl who wanted that baby."

Obviously, her road to motherhood was hardly a fairytale. In a chapter in her book titled "Dear Mr. Cabdriver" she speaks about being single, pregnant and enroute to a doctors appointment. The cabbie, though, got lost.

"S---, goddamn. I mean, why, I mean why the hell-NO! Where are you going now?" Parker yelled (as excerpted in her memoir). In fact, she was laying into the driver to badly that he tried kicking her out of the car.

"I don't want you anymore," he said to her. Mary's response, "No one does ... Look at me . . . My life is worse than yours in this moment ...I am alone. Look, see? I am pregnant and alone. It hurts to even breathe."

She still thinks about that day and her treatment toward this driver.

"This was a complete stranger that met me at a very low moment," she said. "And had I been in touch with a higher self and been forgiving of him, it would've been heroic. But I was so attached to my own unhappiness that I was unable to sort of rise above feeling persecuted, and it just created this dynamic with this perfect stranger... and he held up a mirror at my face, he sort of haunted me because I didn't consider him or his life."

In her book, she apologizes profusely to the unnamed driver.

"I don't know what you thought, if you had a daughter or a wife or if my little drama was a hangnail compared to your life," she wrote. "What I wish I could tell you is that I know it may have been. I don't know what happened to you that morning, or that year, or when you were six. I didn't know your tragedy or hardship and it was grossly unfair of me to compare my life to yours. I am aware of my good fortune. What I don't have to struggle for that makes my life easier than most. I have thought of you and know you wouldn't remember me but I am sorry... I realize now that whatever I was walking through was part of my life, one piece of a bigger story that is mostly beautiful."
