The 'Serenity' actor - who has Levi, 10, Vida, nine, and Livingston, six, with wife Camila Alves - admitted his youngest son, in particular, doesn't always like to talk about his problems so he's come up with a unique physical way to get through disputes.
He said of Livingston: "He's a literal handful, meaning he's the comedian as well as he's the bruiser.
"He sometimes doesn't like to use his words enough to get his point across. He gets a little of that from me, sometimes maybe. I like to wrestle. We have a wrestling mat. When you come in the door that's what we have out there, so if someone's got really something that they want to contest and they don't want to talk about it, let's go up on the wrestling mat, gang."
And when talk show host Ellen DeGeneres pointed out it wasn't fair for a grown man to grapple with a six-year-old, the 49-year-old actor laughed: "I'm the one who comes out of it with the bruises!"
When the 'Gold' star's eldest son turned 10, Matthew and Camila took the youngster to see his favourite band, BTS, and had a great time dancing to the K-Pop group's hits.
