Lady Gaga hit with prop on stage, gets concussion

Lady Gaga suffered a concussion after being hit on the head by a pole during a concert in New Zealand on Sunday.

A YouTube video shows a back-up performer accidentally striking Lady Gaga with the prop while removing it from the stage.

The singer staggered a bit, rubbed her head, briefly left the stage and then returned to finish the show.

Lady Gaga's makeup artist tweeted that the singer had a concussion, but was going to be OK.
