She’s played everyone from Marie Antoinette to one of the most beautiful women in history, Helen of Troy, and she speaks three languages fluently; yet somehow the talented and stunning Diane Kruger has remained one of the most down-to-earth celebrities out there.

She’s just as comfortable strolling casually on the streets of Vancouver with her man of seven years, Joshua Jackson, as she is sitting front row at the hottest runway shows in Paris.

In the August issue of Marie Claire UK, the star shares some surprising secrets to the success of their relationship. “There’s never going to be a role that’s more interesting than my own life,”; she reveals. “I’m grateful that I met a person who feels the same, not just about me, but also about our relationship. But therapy helps, too.”;

Yes, she is honest and open about her struggles: “My friends ask, “what’s wrong with you?’ 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.”;

As for keeping things steamy between herself and the Fringe star, nothing beats getting naked during a hot spell for a romantic skinny dip. “Look, it gets so hot in the summer, it’s like 80 degrees at night, and you’re in the middle of nature… wouldn’t you?”; asks the 36-year-old blonde beauty.
