Matthew McConaughey barely spoke to his mother for eight years after she spilled the details of their weekly phone chats

He told PEOPLE: "I'd say we're closer now ... We had about an eight-year period where I had to have short conversations with her on our Sunday phone calls because she was sharing a lot of that information.

"I'd tell her something on Sunday between son and mom, and Tuesday I'd read about it in the news or see it in the local paper. She couldn't help herself."

Kay added: "We were on a hiatus."

Matthew went on to insist they still talked regularly, but he refused to have deep and meaningful conversations with her.

He said: "We had some boring conversations on Sunday. I wouldn't tell you s***."

During the interview, it was revealed Matthew hit pause on their relationship after Kay let a TV crew take a tour of the actor's childhood home, but she's adamant she was just showing off because she was so proud of her son.

She said: "I took people through the house and said: 'Well, this is where Matthew slept'. Someone called him and said: 'Are you watching what your mama's doing?' But I was so proud that I was just telling the world."

Matthew added of the incident: "I call her, she answers the phone. I go: 'Mom, what'd you do?' She says: 'What?' I said: 'Don't tell me. What?' I could hear the same show I was watching that she's taking the camera through the house in the background.

"She goes: 'Oh, that. I didn't think you'd find out.' "

However, Matthew eventually forgave her and no doesn't care if she spills his secrets in public.

He concluded: "I got stable enough with my own position and fame that I was like, you know what? My mom can say whatever the hell she wants. Let's take the lasso off and just go for it, Mom."
