Megan Fox is looking back at past abusive relationships with famous partners that she’s kept secret.

The Jennifer’s Body actress writes about toxic relationships and themes of abuse in her new book of poetry тιтled Pretty Boys Are Poisonous.

In an interview with Good Morning America that aired Tuesday, Fox, 37, talked about finding a creative outlet to delve into her “horrific” past relationships.

“This is not an exposé that I wrote or a memoir. … But throughout my life I have been in at least one physically abusive relationship and several psychologically very abusive relationships,” she said.

“I have only been publicly connected to a few people, but I shared energy with, I guess we could say, who were horrific people. And also very famous — very famous — people,” Fox said. “But no one knows that I was involved with those people.”
