McConaughey: 'Language barriers are good'

Matthew McConaughey has revealed that he cannot grasp girlfriend Camila Alves's native language.

The How To Lose A Guy In 10 Days star, who has son Levi and daughter Vida with Alves, said that the language barrier is healthy for their relationship because she can talk about him without him realising.

McConaughey told Jay Leno on his show: "Levi speaks a whole lot more Portuguese than Papa does. I get a little heck for it in the household.

"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."
