Matthew Mcconaughey insists the language barrier between him and his Portuguese girlfriend Camila Alves is actually beneficial to their relationship - because she can moan about the actor without him knowing.
The Hollywood star has two children with the Brazilian model/designer, but he's never learned to speak in his partner's native tongue.
And MCConaughey is convinced his lack of linguistic skills helps keep their romance alive.
He tells U.S. talk show host Jay Leno, "I've come to find that I do think it is actually healthy for our relationship that I don't speak that much Portuguese because she doesn't have to whisper if she's talking noise on me. She can speak out loud.
"I don't know what she's saying, but it sounds great... someone can say something about you right in front of your face and you don't even know it's about you."
The actor also reveals the couple's son Levi, who turns two this summer (10), can already speak more Portuguese than his dad.
He adds, "Levi speaks a whole lot more Portuguese than Papa does. I get a little heck for it in the household."
