The 2011 Metropolitan Opera kicked off the fall season on Monday with Gaetano Donizetti's Anna Bolena starring opera singer, Anna Netrebko.
From New York City's wealthiest man, David Koch, to Tyra Banks, the varied crowd was out to celebrate a night of high-brow culture.
We've got the photos below, including one of model Crystal Renn's "unrecognizable" weight loss. Austin Scarlett of Bravo's Project Runway also makes an appearance. Take a look! And if you're so moved by this slideshow that you need to see some opera, buy your tickets here.
