The ladies gracing the pages of the Sports Illustrated Swimsuit issue turned out in NYC last night to celebrate the edition's publication. This year's cover model Irina Shayk led the proceedings, just as 2010's honoree Brooklyn Decker did last February. Irina and Brooklyn are both featured in their bikinis, as are other models like Chrissy Teigen, Hilary Rhoda, and Cintia Dicker. All of the girls stepped out for the party, with Chrissy even having her man John Legend on her arm after their adorable appearance at Sunday's Grammys. It was a night for Irina to let loose with her friends following a press tour to promote the magazine, which included dishing all about her fitness routine.
