Legendary singer-songwriter Carly Simon has a memoir coming out, Boys in the Trees, and has spoken to People in advance. A sad revelation came up in the process: Simon was sexually abused at the age of 7 by a teenaged male, a family friend.

Simon, now 70, admits she found herself wanting "to keep it quiet because I wanted to keep it going." She explains:

"I was devastated because I thought I was in a romance. Which I think happens to a lot of girls. Your libido overpowers everything! You’re so libidinous even at the age of nine and ten. And sometimes there’s an outlet there. I bet in many more cases than we know about there is."

Simon told her sisters about the situation at the time; they didn't believe her until receiving copies of the memoir. "It was heinous," she tells the magazine. "It changed my view about sex for a long time."

Boys in the Trees: A Memoir will be released Nov. 24. If you or someone you know needs help, the Rape, Abuse & Incest National Network is available around the clock.
