Natalie Portman unleashes her Black Swan sensuality in a new commercial for Miss Dior Cherie perfume that pushes the limit on her pledge never to get undressed again in front of a camera.

The new ad is hyper romantic and sensual with Serge Gainsbourg and Jane Birkin singing their sexy French song “Je t’aime… moi non plus.”

The literal translation of the title is “I love you… me neither.” Gainsbourg wrote and sang it with Brigitte Bardot in 1967, but the most popular version is the one he recorded two years later with Birkin, who was his lover at the time. The song’s been covered by everyone from Donna Summer to Madonna.

Dior spared no expense for the 20-second spot. It hired Hollywood Director Sofia Coppola, whose credits include a screen-writing Oscar for “Lost in Translation,” “The Virgin Suicides” and her latest film “The Bling Ring,” with Emma Watson.

‘I love Sofia Coppola’s whole aesthetic. She presents herself in a ladylike fashion and has so much personality,” Portman said of the director.

The commercial is filmed as a homage to Jean Luc Godard the legendary 1960s film director and pioneer of “new wave” cinema. It opens with a kiss between Portman, 31, and a male model, whom she described as a 20-year-old. “I feel like an old cougar,” she told Women’s Wear Daily, about making the clip.

The couple kiss suggesting they are about to make love, and Portman unties the bow tie of his tuxedo. She’s also pictured soaking in a bathtub wearing sun glasses and looking dreamily erotic in a strapless black dress on an Old World balcony.
