Kate Moss in the Virgin Mobile adKate Moss in the Virgin Mobile adAs Yazz once said, the only way is up for Kate Moss nowadays.

Not that Yazz was specifically referring to the supermodel, but with Kate's comeback since her drug scandal, she could well have been.

It seems Kate has been inundated with work since completing her rehab treatment in the States.

Her latest work has seen her veering into the world of acting, as she stars in Virgin Mobile's new advert.

Wearing a beige v-neck jumper, grey shorts and a mere scraping of make-up, Kate receives a call from a man named Kyle saying he has found a perfect contract for her.

He discusses the merits of the contract and signs on her behalf.

Cunning.

Sir Richard Branson said he was "thrilled" the "best model in the world" had agreed to work with the Virgin Group.

"I have known Kate Moss for 18 years, and am a huge fan of hers both personally and professionally.

"She looks absolutely stunning in the new Virgin Mobile ad and she will impress a lot of people with her natural beauty, acting skills, great comic timing and her ability to poke fun at herself," he said.

The ad premieres on Christmas Eve.
