One of Madonna's New York neighbors says the superstar's loud music and frequent dance sessions are causing a commotion.

Karen George, who lives above Madonna in a building on Central Park, said in a lawsuit filed Friday against the building's co-op board stating that the 'Material Girl' is using her apartment as a rehearsal studio, forcing neighbors to endure "blaring music, stomping and shaking walls," for up to three hours each day. The building's board says it has already threatened to evict Madonna.
