Los Angeles, July 9 :  Actress Diane Kruger says she has a simple beauty regime, though it can sometimes be difficult to maintain it.

"I try to get nine hours of sleep a night. It's really that simple. Of course, it's hard to do sometimes, especially when I am working, but I feel and look better when I sleep well," contactmusic.com quoted Kruger as saying.

"I also noticed a great improvement in my skin when I gave up smoking. There are no secret potions, though," she added.

The 35-year-old prefers women who maintain a simple look.

"I have always liked interesting people. I trained originally as a ballet dancer so I have always admired the simple elegance of the ballerina, the refined features and serenity, and hair pulled back in a bun. I like a simple, clean look rather than elaborate beauty. Grace Kelly and Romy Schneider both inspire me," she said.
