Lady Gaga will appear in Sin City: A Dame to Kill For in what appears to be a cameo role and potentially more.

Joseph Gordon-Levitt recently revealed the news about his upcoming co-star in an interview on Boston Radio Station Jam’n 94.5.  The topic was raised due to them being spotted talking to at the MTV Video Music Awards 2013.  JGL was present for Gaga’s audition and he states that she “nailed it.”

“She was in ‘Sin City 2.’ I did a part for [it]. Mr. Rodriguez asked me to be in, and Lady Gaga is in a scene of it. And I gotta say, she did a really good job,” the actor said. “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. So it was good to see her again [at the VMAs].”

Sin City: A Dame to Kill For will be in theaters on August 22, 2014.
