Famously known as Marcia Brady, the eldest girl with hair of gold from the iconic sitcom "The Brady Bunch," Maureen McCormick is now spilling the beans on how she messed up her life as a promising child star in a tell-all book about her drug addictions, sex life, and how she dated Michael Jackson, Steve Martin, and her onscreen brother Greg, played by Barry Williams.  

If you have been wondering what Maureen McCormick has been up to lo these many decades since the show went off the air, wait no longer: the former child star has just released her memoir titled "Here’s the Story: Surviving Marcia Brady and Finding My True Voice."

Just like the fate of many other famous children, Maureen was exposed to drugs, partying and out-of-control behavior. The main difference is that she was able to do it mostly under the radar in the age before tabloids and paparazzi.

Now 52 years old, Maureen, who was on the "Today" show promoting her book, recalled her unusual string of relationships with actor Steve Martin, Michael Jackson and Barry Williams, and also revealed that she once traded sex for drugs and engaged in full-on binges at the Playboy Mansion and at the home of Sammy Davis Jr. The actress said she nearly hit bottom with her drug abuse that one time when in a quest for cocaine she ended up naked in front of the video camera of a guy she met at the Playboy mansion.

"I was supposed to be at the studio, screen testing to pick the guy that would play my husband," she recalled. "I had been up for three days doing coke and was playing solitaire in my closet. My agent had to go to the sixth floor, climb into my place, tear off my clothes and get me in the shower. He said, 'You have to get to Paramount right now, and you have a problem.' I couldn't hide anymore. Everyone knew. ... I had an extremely addictive personality, and drugs just took over my life."

Instead of sending her to rehab, the "Brady" producers hooked her up with "shrink to the stars" Eugene Landy, who later was taken down over his negligent treatment of Beach Boy Brian Wilson.

"As a teenager, I had no idea that few people are everything they present to the outside world," McCormick wrote in her book, excerpts of which were just released. "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.'"

Once the "Brady Bunch" ended, McCormick was sucked into an addictive hard partying lifestyle, taking drugs like cocaine and Quaalude’s, a sedative drug. Her last attempts to upkeep her career, by landing a few movie/TV roles, failed because she was ultimately shunned for her unreliability due to drug use.

Over the past years, McCormick became a small reality star, showing up on "Outsider’s Inn" and winning "Celebrity Fit Club."
