Master illusionist David Blaine kicked off his Up-inspired stunt, Ascension, on the morning of Sept. 2 in Page, Arizona. For the death-defying stunt, David will soar through the air at an elevation up to 18,000 feet holding onto nothing but a cluster of 52 helium-filled balloons — one of which is actually an “experimental aircraft.” And while we’re all familiar with David Blaine and his daredevil illusions and stunts, we’re curious to know more about his family life — including his ex-fiancé, Alizée Guinochet.
