During a Wednesday night visit to 'Late Night with Jimmy Fallon,' Wintour spoke about this year's Metropolitan Museum Costume Institute Gala and Gaga's pre-show rituals, and a specific incident which didn't sit well with Wintour.
"We had Lady Gaga this year," said Wintour. "There was a moment when she was communing with God and she was praying in the back, waiting for God to tell her it was all right to go actually onstage."
Apparently Gaga had a very long chat with God, which clearly annoyed the real queen of fashion. "Fortunately he gave her the message after 45 minutes," she quipped.
Fallon jokingly replied, "I always talk to God, too -- whenever he says I can start the show. He books a lot of acts in New York City," he quipped.
"You know how to throw a party," he told Wintour. "It's so well organized. The biggest of the bigs in fashion, and everybody's got these beautiful gowns. You have a few drinks and then a crazy awesome performance."
