Although she's in a relationship with longtime boyfriend Joshua Jackson, don't expect Diane Kruger to walk down the aisle again any time soon.

"Without sounding pessimistic, I learned that I don't believe in marriage," she tells Glamour. (The actress was married to French actor Guillaume Canet from 2001 to 2006.)

"I believe in a commitment that you make in your heart. There's no paper that will make you stay," she adds.

In the magazine, Kruger also admits to being fashion obsessed. "I truly, genuinely like clothes. Making them is an art form, and wearing them is a form of self-expression. I find it very emotional because I can remember moments in my life -- my mood, how I felt -- through these clothes," she says.

The 'Inglourious Basterds' star helps Jackson out with his style. "We go shopping. But he likes it. I definitely wasn't fond of these blue sneakers that he wore all the time for about a year and a half."
