The intimate ceremony took place Saturday in NYC, and was followed by a more lavish reception at the Grill Room.
Emily Ratajkowski was chic in yellow.
Some of the bold-print names to show up for the reception include Anna Wintour, Rita Ora, Justin Theroux, Emily Ratajkowski, Lil' Kim and a bevy of supermodels: Kate Moss, Naomi Campbell, Gigi and Bella Hadid, Kaia Gerber and more.
Justin Theroux was festive in stripes.
The grooms wore dark green tuxes and held hands while posing for photos outside the venue, having been chauffeured there in a classic automobile. The venue itself also had a "green" theme — decorated with trees and pink blossoms.
Rita Ora was one of the most colorful guests.
The white, multi-tiered wedding cake came courtesy of Ron Ben Israel of "Sweet Genius," and guests were given sweatshirts bearing the image of two squirrels as mementos. "Don't float away" was printed on the shirts, but guests were definitely in seventh heaven as the place was converted into a night club for an all-out dance party.
The Hadids arrived in style!
