Karen George, of Manhattan, lives above Madonna in a building on Central Park. She said in a lawsuit filed Friday against the building’s co-op board that Madonna 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.  That Madonna must have some energy, George complained about “unreasonably high decibel, amplified music” and vibrations pouring through walls, ceilings and radiators. The building’s board says it has already threatened to evict Madonna.
