The “Ghosts of Girlfriends Past” actor claims nine-month-old Levi – his son with his Brazilian girlfriend Camila Alves – is always delighted when he manages to squirt him with urine at changing time.
He said: “Yes, I’ve changed diapers and yes, Levi has peed on me – more than a few times to both.”
“He gets the joke when he pees on me. He laughs. He laughs his butt off!”
“I think I am good at changing diapers. I could have a race-off with some other dads out there.”
Despite his son’s penchant for soaking him, Matthew loves being a parent.
The 39-year-old actor says becoming a father has helped him find joy in life, explaining just seeing his son smile makes him happy.
He revealed to People magazine: “The coolest thing I’ve learned from Levi is kids really remind you of your sense of humor.”
“Like I was just saying, they pee on you and they’re just laughing and all of sudden you’re reminded of having a sense of humor about everything.”
“You can watch Levi, and everything he sees is for the first time, so you see the wonder in something we see every day.”
