Anna Wintour on David Letterman

Anna Wintour appeared on David Letterman Monday night to sit down and discuss The September Issue, Vogue, and the Fashion Night Out event (she's going to be at Macy's on September 10th!). Although I missed the segment, I was able to find a clip online. Anna showed her sense of humor, proving that she's not completely an ice queen! Anna, you rocked!
