Kristen Stewart has stripped down in the name of fashion. The “Twilight” actress has bared all in a revealing picture taken by photographer Mario Testino for his Towel Series.

The usually shy actress has shed off all her inhibitions in the racy photoshoot, where she uses only a towel to cover her modesty. Testino shared the sensational black and white picture on his Instagram page Thursday.

“TOWEL SERIES 91, KRISTEN STEWART. #MarioTestino #TowelSeries,” he captioned the photo, which received many praiseworthy comments from the actress' fans.

Stewart is not the only actress to pose nude for Testino's Towel Series, in fact she is the 91st. The photographer has created a series of glamorous black and white portraits of various models and celebrities, wearing nothing but a towel.

The Towel Series campaign was kicked off by model Kate Moss, when she tied her hair on top of her head and wrapped them in a towel, Metro UK reported.

“The Towel Series is a private club,” the 60-year-old British photographer told Vogue last year. “I choose very carefully who I photograph for it — it is only my point of view, no one else has a say in it.”

Other celebs, who posed for the glamorous series, include Vogue editor Anna Wintour, Cody Simpson and her ex-girlfriend Gigi Hadid, Miley Cyrus, Keira Knightley, Justin Bieber, Cara Delevingne, Naomi Campbell, Selena Gomez, Emily Ratajowski, Amanda Seyfried, Cristiano Ronaldo and Kate Moss.

In other news, Stewart's latest film “Equals” has landed a television deal with DirecTV, where it will premiere first. Stewart stars with Nicholas Hoult in this science fiction love story. The two actors attended the world premiere of “Equals” at the Venice Film Festival last month.

The 25-year-old is currently busy shooting for an untitled Woody Allen film, where she stars alongside Jessie Eisenberg. Other actors in the film include Blake Lively, Bruce Willis, Corey Stoll, Anna Camp, Parker Posey, Paul Schneider and Judy Davis.
