Lionel Richie was admitted to a St. Louis intensive care unit after performing at The Muny in Forest Park on Saturday night, according to TMZ sources with direct knowledge. The singer reportedly checked into a local hospital for testing, with doctors evaluating possible mild dehydration. People who attended the concert told TMZ that Lionel Richie appeared to struggle near the end of the set. During “All Night Long,” the 76-year-old performer reportedly asked his team to bring out a chair so he could finish the song while seated. Another Health Scare for Lionel Richie? Lionel Richie’s latest hospital visit follows a June incident in St. Paul, Minnesota, when he became ill during a concert and ended the performance early. Lionel Richie told the crowd he felt “dizzy” and “strange” before paramedics took him backstage and transported him to a hospital by ambulance. According to TMZ, Lionel Richie was hoping to leave the St. Louis hospital Tuesday as doctors continued checking him. Representatives for Lionel Richie had not publicly commented at the time of publication, so there is no confirmed diagnosis beyond the reported concern about dehydration.
