John Demsey, the group president at the Estée Lauder Cos. who oversees the M.A.C Cosmetics, Tom Ford Beauty, Estée Lauder, and Sean John Fragrances empires, has a new title on his polished resumé: fiancé. Demsey proposed to his girlfriend Anouschka Izmirlian over the weekend in the kitchen of his apartment at the Museum Tower in Midtown. However, unlike Demsey’s well-executed product launches, his engagement wasn’t without a hiccup; the ring wasn’t ready in time, so the bride-to-be was presented with a Kimora Lee Simmons Hello Kitty ring by her quick-thinking beau. Naturally, she said yes. “We’ve known each other for over a decade,” Demsey, who first met his fiancé in an elevator, said. That's fairy tale true love!
