Actress Mischa Barton is fronting a new campaign for an electronic cigarette company.

The O.C. star is the lead judge for Vapestick's Style Icon drive, which aims to find Britain's most stylish user of the devices.

Entrants are asked to strike a pose with one of the brand's electronic smokes to be in with a chance of becoming the face of its future advertising initiatives.

Barton is fronting the campaign and has posed for a photoshoot in which she is seen smoking the company's electronic cigarettes.
