Anna Wintour and Sienna Miller hit the red carpet together at the premiere of The September Issue at the MoMA in NYC last night. The Vogue editor and the movie's featured cover model shared a few laughs as Anna hosted the designer-studded event. Diddy, Marc Jacobs and Renee Zellweger were among the big names who came out to support the movie, which centers around the making of the September 2007 Vogue featuring Sienna. The magazine world has changed a lot since then, but the mood seemed cheery as Anna becomes a big screen star and prepares for ad libbing her appearance on Letterman next Monday.
