Los Angeles: Singer Lady Gaga will feature in a cameo in upcoming action movie "Sin City: A Dame to Kill For".
Gaga, who recently released her album "ARTPOP", behaved like a complete professional on the sets of the movie, reveals her co-star Joseph Gordon-Levitt, reports contactmusic.com.
"Lady Gaga is in a scene in it, and I got to say she did a really good job, like she's a great actress. And I didn't know that," Gordon-Levitt said.
The singer's confidence surprised Gordon-Levitt, who plays the role of Johnny in the movie.
"You know she came in and I was like 'Okay 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," he said.
Co-directed by Robert Rodriguez and Frank Miller, "Sin City: A Dame to Kill For" is a sequel to 2005 movie "Sin City".
