Natalie Portman may have bared all in her previous campaigns for Christian Dior, but she is covering up in her latest advert for the French fashion house.

Natalie Portman, 31, is the epitome of demure chic in the gorgeous shoot and is seen softly gazing at the camera while wearing a white knitted jumper.

In another shot, the actress is pictured looking especially casual in a simple dark grey top and artfully worn in jeans.

But it’s not all about dressing down for Natalie Portman, in a final stunning image she is seen sitting on a bed wearing a diaphanous pastel pink dress.

The shoot is a stark contrast to her most recent advert for the Diorskin Nude range, where the brunette beauty is pictured lying topless over a chaise lounge.

Natalie Portman also stripped off for her previous advert for Miss Dior Cherie perfume, where she soaks in a tub wearing nothing but her Dior sunglasses.

Directed by Sofia Coppola, the homage to Jean Luc Godard’s 1960s movies, also shows the actress undressing her onscreen lover and kissing him passionately on a bed.

Wearing a black strapless dress the star, smoulders for the camera and poses suggestively with a black bow-tie.

Natalie Portman might look totally at ease in front of the cameras but in a recent interview with InStyle, the actress confessed that she feels as if she never quite succeeds in putting on a perfect public appearance.

“My grandmother believes you don’t leave the house unless you have perfect hair and make-up, so she is always at me for not brushing my hair or not putting on enough make-up,” she said.

“I love Sofia Coppola’s whole aesthetic. She presents herself in a ladylike fashion and has so much personality,” the mother of one-year old boy Aleph added.

That said, Natalie Portman did admit that she never leaves the house without a lipstick: “I keep three lipsticks with me, always, one nude, everyday color, plus a red and a plum for dressing up.”
