Lady Gaga has been struck on the head by a pole while performing a concert in New Zealand.
The singer was hit during the third of three shows in Auckland.
Clips posted online show a back-up performer accidentally striking Gaga with the set prop while removing it from the central stage.
Gaga, holding a mock machine gun, staggers and rubs her head before briefly leaving the stage. She continued the show, part of a world tour.
Gaga's make-up artist Tara Savelo wrote on Twitter: "Gaga has a concussion but she is going to be okay ... can't believe she finished the show."
The singer's New Zealand publicist Bridget de Launay said she was seeking comment from tour organisers, adding the Auckland shows were sell-outs and a "huge success".
