It was a winning evening for Fergie and director Quentin Tarantino last night in Vegas, where a star-studded crowd turned out to help them celebrate their birthdays. Vivica A. Fox, Kid Rock, rapper Nelly, Fergie's fiancé Josh Duhamel and Daryl Hannah all made their way to Jet at the Mirage to toast the birthday boy and girl, who hit it off while filming a steamy scene in the director's 2007 campy gorefest Grindhouse. The two started their special night by taking in the 7 p.m. Cirque du Soleil Beatles-themed show, LOVE, and met the rest of the revelers at Jet afterward. Word is a playful, late-night cake fight erupted between Fergie and Quentin, still kids at heart at the ages of 33 and 45, respectively. Who knows if they won any loot at the gaming tables while in Vegas, but Fergie certainly looked like a million bucks in her matching diamond-patterned handbag and heels.
