It was 117 degrees in Las Vegas but that didn't stop SI Swimsuit models Chrissy Teigen, Nina Agdal, Alyssa Miller, Genevieve Morton, Julie Henderson and Kate Bock from partying it up at SI's “Summer of Swim” event at the Wynn Las Vegas on Friday. The one day event started poolside as Chrissy, Nina, Alyssa and Kate joined resident DJs Sultan and Ned Shepard at the 55,000 square-foot Encore Beach Club. After a short break, the four models met Julie and Genevieve to walk the red carpet. Afterwards, it was onto Surrender Nightclub at the Wynn as Swedish DJ duo Cazzette spun tunes until the wee hours of the morning. We don't blame you if you missed the action -- it was 117 degrees, after all -- so here is a massive photo gallery of the event.
