Lady GaGa accidentally knocked one of her dancers' teeth out during a show in New York last night (March 31).

The 24-year-old singer is reported to have eagerly swung her microphone at the Party 105 show when it inadvertently hit the dancer in the face and knocked three of her teeth out.

The gap-toothed dancer is reportedly okay after the incident, with GaGa – real name Stefani Germanotta – paying for dental treatment, reports The Sun.

Lady GaGa is yet to comment on the incident.
