Toward the end of the video, Azalea stops "Black Widow" as medics rushed the stage to aid the dancer.

The 28-year-old later addressed the incident online saying, "Hey guys, just want to let everyone asking know my dancer is OKAY! The lights & heat caused her to have a seizure. She is backstage feeling much better."

Azalea continued on her Instagram Story, " I thought she had just fallen/twisted her ankle,” she continued. “And it may sound harsh but; you keep singing until music stops & ask for a medic which is what I did. We are all really shaken up by what happened & just thankful she is okay."

She then asked her fans to refrain from turning the video of the event into a meme or joke.

"I know it’s easy to make memes of someone ‘passed out’ but someone having a seizure isn’t funny, it’s really scary! So I hope my fans do not repost some of the memes I’m seeing about my dancer."
