A Rihanna concert in Dallas, TX ended early Friday night, after a fire caused the pop singer to exit the stage.

A video posted on YouTube shows a fire burning at the top of the stage at the American Airlines Center, with some sparks falling toward the floor. Some people begin to stream out.

The R&B and pop star posted several messages on Twitter following the incident.

“DALLAS!!! We set the stage on FYAH tonight!!! LITERALLY!!! I’m so (mad), I was havin so much fun wit yall too!!! I gotta come back man!!” the singer tweeted.

Dallas Fire-Rescue Captain Johnny Bates said a chair caught on fire.
