Chris Martin has the typically British stiff upper lip, wife Gwyneth Paltrow has revealed.
The Oscar-winning actress admitted she often has to encourage the Coldplay frontman, with whom she has two children, to express his feelings.
"I definitely have to coax things out of him when we talk - you know, he's British, so it's a different lexicon totally," she told the US edition of Good Housekeeping.
"But you have to communicate. Otherwise there's no relationship," she added.
Despite their reluctance to be photographed together in public, Gwyneth, who next stars in Country Strong, said their relationship is as strong as ever.
"I can depend on him. He makes me laugh. He's really appreciative of me. You know, he makes me feel special," she gushed.
The 38-year-old also opened up about her battle with post-natal depression, following the birth of four-year-old son Moses.
"I felt like a zombie. I couldn't access my heart. I couldn't access my emotions. I couldn't connect," she admitted.
"It was terrible, it was the exact opposite of what had happened when Apple was born. With her, I was on cloud nine. I couldn't believe it wasn't the same. I just thought it meant I was a terrible mother and a terrible person."
Gwyneth added: "I thought postpartum depression meant you were sobbing every single day and incapable of looking after a child. But there are different shades of it and depths of it. It was a trying time. I felt like a failure."
