Designer Marc Jacobs and Vogue Editor In Chief Anna Wintour with Late Night Host Jimmy Fallon.

Jimmy Fallon is a nervous fellow by nature, but he shirked that college humor to the side a smidge to welcome fashion legends designer Marc Jacobs and Vogue E-I-C Anna Wintour to his stage this week so the two can plug her upcoming Fashion’s Night Out coming up September 10.

Anna was light on the glaring and kept the topic on point, even interrupting Marc Jacobs’ subway story, and looked amazing in Carolina Herrera and her signature bob a-swaying while MJ rocked a kilt.

And while Jimmy gushed about the first lady of fashion’s annual Met Gala where Lady Gaga performed this year, the Wintour wasn’t exactly gaga over the pop princess’ time management by daring to keep Anna waiting while LG chatted with a higher power. “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.”

With a roll of an eye and bat of a eye, Wintour quipped, “Fortunately he gave her the message after 45 minutes,” she quipped.
