Who's the fairest in all the Milky Way? We'll find out tonight when the Miss Universe pageant airs live from Las Vegas on NBC at 8 p.m. EST! Last year, Leila Lopes from the African country of Angola (above, center) took home the top tiara, beating out 88 other contestants for bragging rights and a year-long contract as a goodwill ambassador for The Miss Universe Organization, complete with luxury apartment and scholarship, and $84,000 of additional prizes. Bubbling Bravo personality Andy Cohen and E!'s Giuliana Rancic will play co-hosts to tonight's events, with celebrity stylist Brad Goreski serving as one of the judges alongside singer Cee Lo Green, fashion photographer Nigel Barker, and Kourtney Kardashian's husband Scott Disick. Cohen is already in heavy preparations for the show, as he Tweeted that he was in a tux by 10 a.m. this morning, and Instagrammed a shot of Miss USA, Rhode Island's Olivia Culpo, backstage. Tune in tonight to see Culpo and all the other contestants from every corner of the known universe compete for the crown!
