Who knew seeing Beyonce in concert could be so dangerous? At a concert in St. Louis last night, 2 fans in the front row were injured and sent to the emergency room when pyrotechnics at the concert spilled into the front row. Yikes! Afterwards, Beyonce is reported to have visited the injured fans, who are expected to make a full recovery, at the hospital. Soon after the concert, Knowles arrived tat 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. Knowles, 25, met with the fans for about 45 minutes. I just thought it was a great thing for someone of her stature to do, Williams said.
