Scarlett Johansson's showing off her bubbly side.

The actress and celebrity ambassador for Moët & Chandon Champagne (since 2009), stars in the brand's latest campaign, photographed by Tim Walker, who shoots her in his trademark romantic style.

The face of Mango puts that famous pucker to use, pouting seductively in bright red lipstick. In another shot, she poses on a wooden staircase, surrounded by towers of champagne glasses and clutching a magnum of Champagne, while wearing a gorgeous sky blue ballgown which alluringly reveals a bit of the sex symbol's thigh and leg.

The Huffington Post reports that the President and CEO of Moët & Chandon, Daniel Lalonde, said of the new ad: "Moët & Chandon, the most loved champagne since 1743, is a universal symbol of joie de vivre and success. This new campaign highlights a return to the immutable elegance and glamour that are inherent to both Moët and Scarlett."

Elegance, glamour... and lots of sex appeal. Bottoms up!
