Patti LaBelle sat down on the stage and cried in a performance Saturday night at an outdoor festival. "I've never been this embarrassed in my life," the Grammy winner said of her reaction to the cold weather. "This sucks. It's the worst show I've ever done in my life." The star was the festival's headliner and didn't hit the stage until after midnight, after crew members had tried to warm her up backstage with socks, gloves and wraps.
