(WJW) – John Stamos reveals he was sexually abused by a babysitter.

PEOPLE reports the allegations are detailed in the former Full House star’s upcoming memoir “If You Would Have Told Me.”

Stamos tells PEOPLE, he was around 10 or 11 years old when the alleged abuse took place and that it took writing a book to reflect and acknowledge what had happened.

“It was like you’re playing dead so they’ll stop. But it wasn’t totally aggressive,” he told PEOPLE. “I don’t know, it was not good.”

The Associated Press previously reported that parenthood and the death of Stamos’ friend and co-star Bob Saget helped convince him it was time to write a memoir.

“Honestly, while writing this book I’ve realized I have about a million stories to tell, and I think you may like at least four hundred of them. It has been cathartic and healing and sometimes heartbreaking to dig in and reveal so much,” said Stamos in a previous statement.

Over the years, Stamos has used his celebrity platform to advocate for children. According to his website, he is a Celebrity Ambassador for ChildHelp, an organization that helps the victims of child abuse through education treatment, and prevention programs.
