Kate Upton

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.

Kate Upton unveiled her Sports Illustrated Swimsuit Issue cover with her fellow models on the Late Show in NYC last night. Kate wore a sexy black dress during her appearance on the show, where she and nine other swimsuit models — including Chrissy Teigen, Hannah Davis, Emily DiDonato, and Ariel Meredith — read the top 10 "questions" on the application to become a SI cover model. Some of the joke queries included "Have you ever dated Charlie Sheen?" and "Where's the strangest place you've ever found sand?" Later, Kate bundled up in a black coat to unveil a massive billboard version of her cover that was hung above the Late Show studio. This is Kate's second SI cover in a row, making her the first model to land back-to-back covers since Tyra Banks landed both the 1996 and 1997 publications.

Kate Upton is the 2013 Sports Illustrated Swimsuit Issue cover girl! She posed in skimpy bikini bottoms in chilly Antarctica for the shot, which landed Kate in the coveted spot for the second year in a row. Kate rocked a tiny red suit for the 2012 issue, and her newest snap makes her the first SI swimsuit model to land back-to-back covers since Tyra Banks graced both the 1996 and 1997 publications. Kate spoke to People about her sexy Antartica cover shoot, saying it was "definitely the hardest shoot I've ever done." She continued, "The best as well – Antarctica is one of the most beautiful place I've ever been to. But I'm from Florida, so it was pretty painful." Kate's edition of SI is available on newsstands now.

Hollywood — and the fashion world — had a major love affair with Céline's luggage tote in 2012. Celebrities including Reese Witherspoon, Emma Roberts, Kate Upton, Jordana Brewster, Leighton Meester, and many more were spotted carrying the house's tote in endless varieties. There was classic black, python-print, two-toned, mini, off-white, and the list goes on. Céline has been making these It bags for seasons, so some of them are no longer available. But if you're dying to get your hands on one, check Céline's website, or you can go into any luxury department store to see which styles they carry.
