Two people injured when pyrotechnics went awry at Beyonce Knowles' concert in St. Louis received a surprise emergency room visit from the singer.
The accident happened Sunday night, just as the R&B star's concert began. Broadcast reports said pyrotechnics meant for the stage accidentally spilled into the front row.
Two concertgoers were taken to Barnes-Jewish Hospital. Soon after the concert, Knowles arrived at the hospital, said head nurse Darryl Williams.
"She was just very concerned about the people injured in the audience," Williams said. "It was unannounced and we kept it very low-key so that she could spend time with them."
Hospital spokeswoman Kathy Holleman wouldn't release the names of the concertgoers but said the injuries were minor. Both were expected to make a full recovery.
