Kristen Stewart may be an A-list actress (and a perpetual tabloid target) but her new film role takes her down a few pegs — she's playing Valentine, an assistant to a superstar actress named Maria Enders, in the film Clouds of Sils Maria.

But that's not even the most newsworthy part of the preview! We also see the Twilight grad in nothing but a thong as she becomes her boss's object of lust.

"At the peak of her international career, Maria Enders (Juliette Binoche) is asked to perform in a revival of the play that made her famous twenty years ago," the synopsis for the film starts. "But back then, she played the role of Sigrid, an alluring young girl who disarms and eventually drives her boss Helena to suicide. Now she is being asked to step into the other role, that of the older Helena. She departs with her assistant to rehearse in Sils Maria, a remote region of the Alps."

OK, nothing too dramatic, right? But the plot thickens: "A young Hollywood starlet with a penchant for scandal (Chloe Grace Moretz) is to take on the role of Sigrid, and Maria finds herself on the other side of the mirror, face to face with an ambiguously charming woman who is, in essence, an unsettling reflection of herself."

And, as the trailer shows, sexual chemistry develops between Maria and Valentine. "I don't think it's company figures that's keeping you up at night," Valentine says. "[It's] desire… for me, I think."

So will life imitating art lead to a tragic end? We'll just have to wait for this film to hit theaters stateside to find out!
