Matthew McConaughey has opened up about his "ugly and sometimes violent" childhood in his new memoir, Greenlights.
McConaughey based the memoir on his diary entries over the last 36 years, telling TODAY host Willie Geist that although the way his parents treated him could be considered abuse, he doesn't see it that way.
"I was scared at the moment," he admitted, in response to if he thought their behaviour was wrong. "But even then and immediately after that, I didn't ever question the love that Mum and Dad had, or the love that they gave us."
McConaughey said that some of the stories in Greenlights are "bloody and ugly and sometimes violent" but he wanted to tell them because there were times the love that we [his siblings] had were "challenged, but never had a chance of being beat".
The 50-year-old actor said he hasn't been raising his own children, Levi, 12, daughter Vida, 10 and Livingston, seven, the same way he was brought up, saying he and his wife prefer to "talk things out".
"I don't raise my children the same way my parents raised me ... but I don't dare judge how my parents did it because every single time I got in trouble or got the belt or whatever, I earned it," he said, laughing.
The Dazed and Confused star recently revealed he had been sexually abused as a young person, although said he's "never felt like a victim."
"I have a lot of proof that the world is conspiring to make me happy," he wrote.
McConaughey married Brazilian-American model Camila Alves, 38, in 2012, describing his family as the most "non-negotiable" part of his life.
"Fine ... but the most important thing to me is my family."
