Halsey had to cancel a concert in Maryland after torrential rainfall flooded the venue and soaked awaiting fans.
Social media video from the Merriweather Post Pavilion also showed Halsey's crew kicking a large rodent off the stage toward the drenched fans. Other videos showed rain pouring down onto the crowd, all while the National Weather Service had issued tornado and flood warnings.
According to reports, the concert was delayed, but fans were told Halsey would go on at 10 p.m. However, the show was eventually canceled as flooding turned the venue into a makeshift swimming pool.
"Right now I'm heartbroken and panicked and I just want to know when/that you all get home safely. I love you guys more than anything," the pop star tweeted after the cancelation, later noting that it was too "unsafe" to go on with the show.
In the end, Halsey erred on the side of "safety" but said was unhappy with how the venue handled the situation.
During the storm, fans took to Twitter to indicate they were hiding in bathrooms to escape the storm. Flood waters eventually engulfed the venue.
On Thursday, June 9, Halsey was still thinking about the previous evening.
"Good morning I hope u guys are feeling better this morning after last night's storm," the singer tweeted. "I'm so happy so many of you tweeted me that you got home safe. So Good comes out tonight and I'm gonna camp out on Twitter today n tmrw to talk to y'all about it. Just wanna b close to u [right now]."
