Former 'American Idol' star Jimmy Levy's bag caught fire while his JetBlue flight sat at the gate. Levy said he was told a portable battery inside his bag had caused the fire. In an interview with NBC News, Levy said he was told by investigators his portable charger was to blame for the explosion. "It's a portable charger from a fancy mall, so it wasn't some random thing," he said. JetBlue didn't immediately respond to Insider's request for comment but told NBC News in a statement that its crew "immediately responded and addressed the situation, and there were no requests for medical assistance."
