Bella Thorne was a squeaky clean Disney teen queen less than three years ago. But she’s a full-fledged Hollywood sex siren now. She joins a long list of A-list celebrities for renowned fashion photographer Mario Testino’s towel series. And you know what that means… she’s topless!

Thorne, who only turned 18 in October, is best known for her role as Tancy Henrickson in the fourth season of HBO’s “Big Love,” and as CeCe Jones on the Disney Channel series “Shake It Up.”

She’s made a slew of movies since then, booking six last year and seven films this year. Most, however, were childrens’ and young adult movies like “Alvin and the Chipmunks: The Road Chip,” and teen comedy “The Duff.”

But she’s no kid. She’s made that clear in any number of editorial features and in her latest shoot with Testino, who is known for his high-fashion photography.

Thorne joins a long list of celebs who have posed. Some 24 actors and actresses have stripped down to only a white towel. The celebs include Selena Gomez, Blake Lively, Kristen Stewart, Miley Cyrus and top models like Sukie Waterhouse, Naomi Campbell and Jourdan Dunn.

While there is no overt nudity in the photos (except for Miley!), the photos are sensual and arresting. Bella shows ample side-boob.

Thorne may well be the youngest of the bunch. Check out her photo below and some of the other celebrities who have posed in the series.
