Ms Stewart as we've never seen her before, the starlet sizzles in the simple video, showing off perfect porcelain skin and tousled long locks, dressed in jeans and a plain white t-shirt.

Mixed with shots of the singer himself, K-Stew fades in and out of the background during the three-minute-long music movie, to accompany the first song from Marcus Foster debut album.

It’s thought Kristen agreed to star in the shoot after Robert Pattinson covered another of the upcoming musician's songs – Let Me Sign – for the Twilight Eclipse movie, and for the film’s soundtrack.

Rob’s also been known to cover Marcus's latest track during rare acoustic performances in London.
