Blige, Jean Paul Gaultier, James Corden and Tony Bennett, along with the original five supermodels from Oscar-nominated director David Fincher’s “Freedom! ’90” video: Naomi Campbell, Christy Turlington, Cindy Crawford, Tatjana Patitz and Linda Evangelista, who come together for the first time to discuss their experiences making the iconic music video.
