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

The 31-year-old Black Swan star 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 its not all about dressing down for Natalie, 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 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.

The mother-of-one might look totally at ease in front of the cameras but in a recent interview with InStyle, Natalie 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 did admit that she never leaves the house without a lipstick: 'I keep three lipsticks with me, always, one nude, everyday colour, plus a red and a plum for dressing up.'
