Last month, director Robert Rodriguez made the surprise announcement through his Twitter page that Charlie Sheen is starring as the President of the United States in Machete Kills. Today, the filmmaker made another casting announcement, revealing that pop sensation Lady Gaga is playing a character named La Chameleon. He also debuted a character poster with our first look at the singer in costume. Take a look at the photo, along with his Twitter message.
