Joseph Gordon-Levitt, who plays Johnny in the film, discussed the popstar's role in the sequel to Boston radio station Jam'n 94.5.
He said: "She came in, and I was like, 'Okay, they're having a huge popstar 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."
However, its release date has now been put back until August 2014.
