Kate Upton and her fellow swimsuit models celebrated their new Sports Illustrated Swimsuit Issue with a party in NYC last night. Kate wore a strapless red dress and got into the celebratory spirit by posing with her cover on the red carpet and later mingling with the other models, including Katherine Webb, inside the shindig. Chrissy Teigen wore a sexy floral frock and was joined by boyfriend John Legend , while Irina Shayk worked her stuff for photographers in a skintight purple number. Other model guests included Anne V., Cintia Dicker, and Hannah Davis.
Kate and the Sports Illustrated models have been very busy over the past few days doing press for the magazine, including appearing on the Late Show  on Monday night to read off David Letterman 's famous "Top Ten" list. The special issue — which hit newsstands on Tuesday — features the Sports Illustrated models in bikinis  while visiting all seven continents for their various photo spreads. Notable locales include Irina posing in Spain, Anne dropping by China, and Kate braving the cold in Antarctica to work her stuff in a two-piece.
