Lady Gaga is due to feature in upcoming movie Sin City: A Dame to Kill.

The news was confirmed by actor Joseph Gordon-Levitt, who also stars in the Robert Rodriguez flick.

He revealed that she "nailed" her role in the Sin City sequel, which is due to be released in 2014. He said:

"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!"

The Batman actor added: "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 meanwhile is also set to star in director Rodriguez's Machete Kills, which is due to be released later this year.
