Lady Gaga took to social media to announce her involvement in the upcoming sequel to the 2005 film. She previously worked with Rodriguez on Machete Kills last year.

It seems like acting is something Gaga is enjoying after her roles with Rodriguez and took to Twitter to hint at possible future roles after her touring slows down.

"It's not a big part but I'm always happy to do it!" she told a fan. "When I take a music break I'll have more time."

She added, "I'm just warming up I gotta wet my feet first. Plus I perform best when I have time to focus."

Sin City: A Dame to Kill For is directed by Rodriguez and Miller, from a script written by Miller. The cast includes returning Sin City stars Mickey Rourke, Jessica Alba, Bruce Willis, Rosario Dawson, Powers Boothe and Jaime King alongside newcomers Eva Green, Josh Brolin, Gordon-Levitt, Jamie Chung, Ray Liotta, Haysbert, Juno Temple, Alexa Vega, Christopher Meloni, Gaga, Stacy Ketch, and Jeremy Piven. The film is set for release on August 22.
