The incident occurred near the end of Rexha’s show, bringing the concert to an abrupt conclusion. On Monday morning, she posted a picture of herself on Instagram with the caption, “I’m good.”The incident is just the latest in a dangerous trend of concert goers throwing objects at stars. The motives of the thrower in this case are not known. But in other contexts, over-exuberant fans have tossed phones at stars, not to hit them, but hoping that they’ll get to interact in some way with the star as the phone gets returned.
