The 36-year-old German-born actress said of her romance with Fringe star Joshua: 'All relationships are hard. It doesn't matter what job you have, or how famous or miserable or poor you are.

'It's about commitment. I'm grateful that I met a person who feels the same about me, but also about our relationship. But therapy helps too.'

And Diane doesn't just have relationship therapy, but believes regular sessions with a counsellor can help you stay on track in every aspect of life.

She said: 'It's funny, in Paris people don't talk about it. But here everyone talks about it, and I really like that about America.

'Therapy's not about getting help; it's facilitating yourself to deal better with life in general.'

Diane, who was recently named the new face of Chanel skincare, also opened up about her 15-year friendship with the brand's boss Karl Lagerfeld.

She said: 'I'll be coming home from the local butcher in my sweatpants, just walking up the street when a gold Hummer will come round the corner.

'And the tinted window will come down slowly and it's Karl saying, "Hello, Diane! What's for dinner?" It's so surreal, I love it!'

But while Diane has already had a long and lucrative film career with roles in movies such as National Treasure and Inglorious Basterds, as well as national campaigns, a style icon status and happy relationship, the actress said that turning 30 put things into a whole new perspective for her.

She said: 'Honestly, for a long time I felt that I was so accomplished. "Oh, I speak three languages, I travel the world, I've seen so many things."

'But when I turned 30 I realised I was an idiot. I didn't know s**t about anything.'

The full interview with Diane appears in the August issue of Marie Claire, out 4th July.  Also available as digital edition through Apple Newsstand.
