Angelina Jolie has given birth to a girl and a boy, and dad Brad Pitt took the whole thing in stride. The obstetrician who delivered the twins, Dr. Michel Sussmann, said the babies, Jolie and Pitt “are doing marvelously well.” Jolie gave birth to a boy, Knox Leon, and a girl, Vivienne Marcheline, by Caesarean section about 8 p.m. Saturday in Nice in southern France. Jolie had a local anesthetic and was conscious throughout, the doctor said. Pitt was in the delivery room at the seaside Lenval hospital as the babies were born one minute apart, Sussman said, the boy weighing just over 5 pounds and the girl 5 pounds. “He was perfectly calm and everything went well,” Sussmann said.”He was very happy. The emotion was very strong for him,” the doctor added. “Angelina Jolie was speaking, was laughing with her husband. They were happy. The mother, the babies, the father are doing marvelously well,” he said. Sussmann said the Caesarean was moved forward from its originally planned date “for medical reasons” so the babies could be born “in the best conditions.” The doctor did not give details. He said Jolie is expected to stay in the hospital for a few more days and that she now needs rest. Though the lenses of the world”s paparazzi had been trained on maternity wards across the French Riviera, Jolie managed to slip unobserved into the clinic, reportedly arriving by helicopter on the hospital’s rooftop helipad. Pitt was seen coming and going after Jolie”s hospitalization became public.Paparazzi and curious sightseers gathered outside the hospital in Nice on Sunday, hoping for glimpses and shots of Pitt. Local newspaper, Nice Matin, which first broke news of the birth, reported Sunday that the couple have sold rights for the first photo of their newly enlarged family to an unnamed publication and that the proceeds would go to charity. The first photos of the new twins are expected to bring millions of dollars.
