Angelina Jolie has left the building. Oh, and so have the twins.

Before dawn Saturday, the Hollywood superstar and her newborn twins left the French Riviera hospital where she gave birth a week ago, the hospital said in a statement.

"The mother and her babies are doing very well," reported the Fondation Lenval hospital, located in the southern Mediterranean city of Nice.

Jolie slipped out at 4 a.m. Saturday with the twins, Knox Leon and Vivienne Marcheline Jolie-Pitt, deftly evading most of the paparazzi who have followed the family for months in southern France, ever since Jolie arrived for the Cannes film festival in May. It was not immediately clear if the twins' father, actor Brad Pitt, was with them.

Jolie, 33, checked into the hospital on July 2 and delivered the five-pound babies by caesarean section 10 days later.

Jolie's obstetrician, Dr. Michel Sussmann, told reporters after the birth that the 44-year-old Pitt was at Jolie's side during the delivery, which he said had been pushed up from its originally planned date "for medical reasons" so the babies could be born "in the best conditions."

The Nice-Matin newspaper has reported that an unnamed U.S. publication has paid $11 million US for exclusive rights to the first photos of the Jolie-Pitt twins and that the proceeds will go to charity.

Jolie and Pitt have four other children — Maddox, 6; Pax, 4; Zahara, 3; and Shiloh, 2. Before Jolie checked into the hospital in Nice, the family set up a household in Correns, 100 kilometres away.
