At the Cannes Film Festival in May 2008 , Jolie confirmed that she was expecting twins . For the two weeks she spent in a seaside hospital in Nice , France , reporters and photographers camped outside on the promenade . She gave birth to a son , Knox Léon , and a daughter , Vivienne Marcheline , on July 12 , 2008 . The first pictures of Knox and Vivienne were jointly sold to '' People '' and '' Hello ! '' for a reported $ 14 million — the most expensive celebrity photographs ever taken . All proceeds were donated to the Jolie-Pitt Foundation
