A concert by Rhianna took an unexpected turn Friday night.The singer was performing her Loud Tour in Dallas at the American Airlines Center when some pyrotechnics went haywire during her song, 'California King Bed. 

Rhianna left the stage when a fire broke out above her stage fireworks began to fall down -- cutting her set list short and ending the show early. In watching the video I'm not sure the audience realized that this was not a planned event! They kept cheering until the entire crowd was evacuated from the building and no injuries were reported.
