Kristen Stewart has become the latest celebrity to pose in nothing but a towel for renowned fashion photographer Mario Testino.
The 25-year-old actress looks stunning as she drapes a towel over her shoulder in the intimate black and white image.
Stewart's portrait is the 91st in the photographer's provocative sequence of images, which he shares on his Instagram page.
He describes them on his website as a liberating experience: "I think guys and girls feel this freedom at being able to express themselves because there is no predetermined way of how they should put the towel on.
"You can do anything you want.... Wear it however you want."
He added that they were originally inspired by Kate Moss after he once spied the supermodel wrapped in several towels on the set of a photoshoot.
The Twilight star follows in the footsteps of Selena Gomez, Blake Lively, Justin Bieber and Alex Pettyfer in posing for the series.
