Matthew McConaughey is opening up in his new memoir, Greenlights.

In it, he speaks about his family history, revealing in an excerpt provided to People that his father, James Donald McConaughey, died in bed with wife, Kay.

“I got a call from my Mom. ‘Your dad died.’ My knees buckled,” he writes. “I couldn’t believe it. He was my dad. Nobody or nothing could kill him. Except mom. He’d always told me and my brothers, ‘Boys, when I go, I’m gonna be makin’ love to your mother.’ And that’s what happened. He had a heart attack when he climaxed.

“They were, at times, violent,” he told People in an interview. “As I say in the book, that is how they communicated. They were divorced twice, married three times, I mean, yeah, it was like the Pacific Ocean in a storm.”

Thank you for being so honest, Matthew.
