Madonna Moons Audience in Rome

Madonna outraged the world last week by flashing her nipple onstage in Istanbul. While onstage in Rome Tuesday night, Madonna decided to give fans a peek at another part of her anatomy.

Performing her song "Human Nature," whose chorus states, "I'm not sorry," Madonna unzipped her trousers, slipped them down, turned around and gave the audience a view of her bottom. "Human Nature" was also the song that Madonna was performing in Istanbul when she uncovered her breast.
