Luke Bryan has been dealing with vocal issues since mid-June, and now he's sharing the reason why.

During a show last week, Luke revealed that he's been dealing with COVID-19, and that his voice still isn't entirely back to normal. "You're gonna see me hack. I can't take any more medicine. I can't do anything else, but just try to breathe," he told the audience. The illness caused him to postpone shows and cancel festival appearances. Luke is back to performing, but he's still asking fans to help him hit the high notes when it gets the best of him.
