Brady Bunch alum Maureen McCormick chronicles her battles with addiction and depression and tales of trading sex for drugs in a new memoir entitled Here’s the Story: Surviving Marcia Brady and Finding My True Voice, on sale Tuesday.

In the book, Maureen, who took on the role of Marcia Brady when she was 14, confesses to cocaine binges, an abusive relationship with her father, and an unwanted pregnancy.

“As a teenager, I had no idea that few people are everything they present to the outside world,” the former child star, now 52, writes.

“Yet there I was, hiding the reality of my life behind the unreal perfection of Marcia Brady. … No one suspected the fear that gnawed at me even as I lent my voice to the chorus of Bradys singing, `It’s a Sunshine Day.’”

Maureen says her lifestyle took a positive turn after she married Michael Cummings in 1985.

On Dating Steve Martin:

“I remember him being a very good kisser. But I was insecure and either high or spaced out (most likely both), and I didn’t laugh at his jokes… I’m sure my inability to carry on a normal conversation or respond intelligently put him off. We never spoke again after that date.”

“I’ve always regretted my behaviour because he impressed me as an extraordinary guy. I would’ve enjoyed a second date.”

Maureen on Dating Michael Jackson: “I wondered if he might try to kiss me, but he didn’t.”

Maureen’s Romance with Television Brother Barry Watson (Greg Brady):

“We couldn’t hold back any longer,” Maureen wrote of the young lovers’ first kiss during a period when the show was filming in Hawaii. “It was our first kiss, and it was long, passionate and deep. It was wonderful, too, though as we continued to kiss and press against each other so closely that we could feel each other’s body heat, a part of me — a tiny part, admittedly — said to myself, `Oh my God! I’m kissing my brother. What am I doing?’”

“I’ll always be struck by how much a part of people’s lives Marcia is and always will be. But now I’m not bothered by the connection. It took most of my life, countless mistakes and decades of pain and suffering to reach this point of equanimity and acceptance.”
