When one of Iggy Azalea’s backup dancers collapsed on stage and suffered a seizure during a concert in Brazil, the 28-year-old rapper kept on performing. Backlash was swift and unforgiving. "How can you see someone having a life-threatening emergency and continuing rapping (horribly) over their body,” was one tweet. “She didn't even stop the song so they could make sure the medic was actually present,” read another. Azalea responded to the criticism on Instagram Stories.
