Lady Gaga to Appear in "Sin City: A Dame to Kill For"

Lady Gaga to Appear in

Continuing her promotional duties abroad, Lady Gaga mingled with her fans outside her London hotel on Wednesday evening (August 28) in London, England.

The Applause songstress donned black leggings and a grey blazer, and at one point wore a gas mask, as she posed for pictures with the adoring throng.

Though she has been focusing her efforts on her upcoming album ARTPOP, the 27-year-old also took some time to make an appearance in the film Sin City: A Dame to Kill For.

During a recent radio interview, the films star, Joseph Gordon-Levitt, confirmed Gagas presence in the film and offered up his praise.

He shared, Lady Gaga is in a scene in it, and I gotta say she did a really good job, like shes a great actress. And I didnt know that! You know she came in and I was like OK sure, theyre 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.”

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