The "Where Have You Been" crooner has been cast in Luc Besson's forthcoming sci-fi thriller "Valerian," and while her role is currently unknown, the director promises it's significant.
"She has a big part!" Besson teased on Instagram. "I'm Sooo excited!"
The 27-year-old Barbadian beauty joins a star-studded cast that includes Clive Owen and Dane DeHaan, as well as British supermodel-turned-actress Cara Delevingne.
It's the latest high profile acting gig for Rihanna, who previously starred in "Battleship" in 2012 before landing a leading voice role for DreamWorks' animated comedy "Home" earlier this year.
"Valerian" serves as a film adaptation of Pierre Christin and Jean-Claude Mezieres' epic 1967 graphic novel.
The story is set in the 28th century — when humans discovered how to travel through time.
Production begins in December — around the time when Rihanna is expected to release her eighth studio album, "Anti." The singer says it's an ode to her rebellious lifestyle, which often includes drinking, smoking and getting tattoos.
