The Hollywood star Matthew McConaughey shocked his fans this week by revealing that his father died of a heart attack while he was having sex with his mother.

In an excerpt of his new memoir “Greenlight” that was obtained by People Magazine, McConaughey wrote that his father James Donald McConaughey died just as he always knew he would: making love to his wife Kay.

“I got a call from my Mom. ‘Your dad died.’ My knees buckled. I couldn’t believe it. He was my dad. Nobody or nothing could kill him. Except mom,” McConaughey wrote. “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.”

James died in 1992, and he’d had a tumultuous on-again off-again relationship with Kay, who he married three separate times. McConaughey was conceived just after their third wedding.

“They were, at times, violent,” McConaughey said of his parents. “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.”

These days, McConaughey is the father of three children with his wife Camila Alves: Levi, 12, Vida, 10, and Livingston, 8. While raising three children in quarantine has not been easy, McConaughey and his wife have risen to the occasion.

“They have doubled down on their hobbies, creative things and parts of themselves I don’t think they would have leaned into if they were back in school,” the Oscar-winning actor said. “One of the assets of this COVID quarantine is they’ve been forced to be more self-reliant. They’ve been forced to create their way out of their boredom.”

In the end, McConaughey is loving his life as a dad, as he relishes the role of father as being a “privilege and responsibility.”

“The only thing I ever knew I wanted to be was a father,” the star explained. “And it’s remained the pinnacle for me. Being a dad was always my only dream. … I can’t think of anything being more important.”
