Anna WintourNo one makes 'Vogue' editor-in-chief Anna Wintour wait, but it looks like Lady Gaga never got the memo. 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, which made Wintour roll her eyes in disapproval.

"We had Lady Gaga this year," said Wintour. "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, the 'Bad Romance' singer's talk with the Almighty took over 45 minutes.

Fallon 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.
