Mila Kunis sports natural look for ad campaign

Actress Mila Kunis has gone make-up free for her campaign for Gemfields, supplier of coloured gemstones.

She is seen posing in a messy updo and makeup-free. Her just-woke-up effect is quite stunning, thanks in part to famed photographer Peter Lindbergh, reports eonline.com.

"When we talked though the direction and that the focus was on natural beauty, which really meant no make-up, no blow dry, and no retouching, I have to say I was a little anxious," Kunis told British Vogue magazine.

"Peter has a way of making you feel bare and raw, but in a funny way it's the most beautiful I have ever felt on a photo shoot," she added.
