Joseph Gordon-Levitt has revealed a rather unexpected cameo is in story for Robert Rodriguez and Frank Miller's upcoming Sin City sequel.

Avant garde pop star Lady Gaga is set to appear in the movie in an as-yet unconfirmed role.

The Don Jon actor, who stars in the film as Johnny, told radio station Jam’n 94.5: "Lady Gaga is in a scene in it, and I gotta say she did a really good job, like she’s a great actress. And I didn’t know that!

"You know she came in and I was like 'OK sure, they’re having a huge pop star do a scene in the movie, I understand.' But then she came in and like, nailed it!

"She had her character down, and she was like a total pro, and did a great job, I was really impressed."

Gaga will make her big screen debut as La Chameleón in Rodriguez's Machete Kills, due to hit cinemas later this year.

Josh Brolin, Mickey Rourke, Jessica Alba, Bruce Willis, Rosario Dawson, Jaime King, Eva Green, Dennis Haysbert, Christopher Meloni, Jeremy Piven, Jamie Chung, Ray Liotta, Juno Temple, Julia Garner and Stacy Keach star in Sin City: A Dame to Kill For, due for release in August 2014.
