NICE, France -- The Brangelina twins are here: Angelina 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, said Dr. Michel Sussmann, the obstetrician who delivered the twins.

The 33-year-old actress, the babies and their father, actor Brad Pitt, "are doing marvelously well," 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 weighed just over 5 pounds and the girl 5 pounds.

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." He did not give details.

He said Jolie is expected to stay in the hospital for a few more days.
