Los Angeles - Dwayne 'The Rock' Johnson saved his mother's life.
The 43-year-old revealed he stopped his mum, Ata from committing suicide when he was 15 years old after she got into a blazing row with his father Rocky in Nashville.
He explained on Oprah's Master class: "I knew that my parents were going through some really, really tough times in terms of their marriage. I'll never forget it. It was probably about 1 o'clock in the afternoon. We were at a restaurant, the three of us, and they got into it. They got into a very big fight. Not physical, but just really loud arguing."
"The got into the car, my dad was driving my mom was in the passengers seat."
The Hercules actor goes on to say he remembers driving behind them and seeing them arguing which led his father to stop.
He recalled: "My mom gets out of the car and she had a glazed look over her eyes that I had never seen before. She walks right into the middle of I-65, and continues to walk down into oncoming traffic.
"My heart stopped. I grabbed her and wrestled her over to the side of the road. I don't remember what I said to her.
"I remember she didn't say a thing. In that moment, one of the greatest lessons I've ever learned was how precious life is and how in an instant, it can all go away. It changed me."
The semi-retired professional wrestler has admitted the heartbreaking incident will plague him for the rest of his life.
He said: "It changed me, and the irony of it is that my mom has no idea that it even happened... She doesn't remember a thing, thank God because maybe it's too traumatic to remember."
