The models of Sports Illustrated Swimsuit Edition brought the sin to Sin City on Wednesday, Feb. 13. Cover star Kate Upton showed off her gorgeous curves in a brilliant blue Dior dress while posing on the carpet of the SI Swimsuit on Location event at the Marquee Nightclub at The Cosmopolitan in Las Vegas.
"Vegas with my favorites!" Upton, 20, tweeted while posing with other models -- Anne V, Nina Agdal, Natasha Barnard, Ariel Meredith, Alyssa Miller, Jessica Gomes and more -- that night. The blonde Florida native has earned the cover shot of Sports Illustrated's coveted swimsuit issue two years in a row -- a first-time feat for any model. This year, she had to pose wearing only a parka and swimsuit bottoms while shooting in Antarctica.
"It was freezing!" the blonde Florida native told the TODAY show Tuesday, adding that she suffered frostbite for months afterward. "It wasn't great for me . . . I can't believe we were able to accomplish that."
And Upton's fellow models were ready to celebrate the new issue in Vegas Wednesday. The ladies flaunted their stunning figures while posing with their sexy spreads from the issue on the carpet. The pictorials, featuring 17 models, were shot on seven continents for this year's issue.
"Had so much fun at the SI Swimsuit launch in Vegas last night!" Anne V, 26, tweeted.
Chrissy Teigen was also in attendance and had the support of her fiance, John Legend. The couple, who became engaged in December 2012, looked cozy at the party and posed for an adorable photo together.
"SI Swimsuit has officially touched down in Vegas! I need an IV already," Teigen, 27, joked on Twitter Wednesday. "It's almost like the constant drinking of alcohol isn't helping me get over my cold? What? Confused."
