Marcia Marcia Marcia Is Dishing About Drugs, Romance and Michael Jackson: AP Reports

Maureen McCormick, who tantalized millions of kids as Marcia Brady on “The Brady Bunch” from 1969-74, will come out with a tell-all memoir this week with a mouthful of a title: “Here’s The Story: Surviving Marcia Brady and Finding My True Voice.”

According to the Associated Press, in the memoir, which hits bookstores tomorrow, McCormick, 52, discusses her romance with TV sibling Barry Williams, her dates with Michael Jackson and Steve Martin, cocaine binges and parties at the Playboy Mansion and the home of Sammy Davis Jr., an unwanted pregnancy and trading sex for drugs.

McCormick was 14 when “The Brady Bunch” debuted on ABC. Despite her role as a sunny Miss Perfect, she struggled privately with anxiety and insecurity, the youngest of four children born to a mercurial father who abused and cheated on their mother.
