What a young temptress. While other girls were going through their awkward stage, Niki Taylor was already scorching when she took the fashion world by storm. She started as an aspiring marine biologist, but her dad sent photos of the newly minted teenager to a fashion agency, and since then Niki has worked strictly pumping male biology. By 18, she'd landed an exclusive contract with Cover Girl, achieved the highest number of magazine covers in one year and become the youngest model ever to appear on the cover of Vogue. This hazel-eyed, statuesque beauty amassed a portfolio of hot pix that had guys popping off more than pimples. She appeared on pretty much every magazine cover on the rack, including Harper's Bazaar, Allure, Elle, Mademoiselle, Glamour and Marie Claire. No brainless body, Niki formed her own company and brands herself with sexy calendars. Sadly, the never-shy Niki has yet to appear in any skinematic ventures, though you can get a weekly dose of her all-grown-up lusciousness on Bravo's reality show Make Me a Supermodel. Outside of her sizzling spreads, the only live-action flesh flashed is from Sports Illustrated 1998 Swimsuit Issue Video. It's cheeky, but only a tease at the treasures she's yet to uncover.
