Angelina Jolie will remain with her babies at the Fondation Lenval hospital in Nice, France, as she recovers from the cesarean section and her two babies gain some weight. Dr. Michel Sussmann, the obstetrician who cares for Angelina Jolie, told the local press it may be six or seven days before they are released.

He also dispelled rumors about the mother's health, triggered by a lengthy visit on Monday. "They are all very well, very well," he told People. He also opened up to Europe 1 radio about his role in the birth of the celebrity couple, claiming that he was nervous. "It's true that there was pressure due to the couple's fame," Dr. Michel Sussmann said.

Sussmann also said that both Brad Pitt and Angelina Jolie were calm and cooperative, praising them as "an exemplary father and mother".

Brad Pitt was at the side of his partner Angelina Jolie as she gave birth to the couple's twins, People reports. The babies, a boy, Knox Leon, and a girl, Vivienne Marcheline, weighed around five pounds each and were born via caesarian section little before 8:00 p.m. on Saturday.

Knox arrived first and Vivienne followed shortly. The new members of the Jolie-Pitt family are the fifth and sixth children joining the couple's three adopted kids Maddox, 6, Pax, 4, Zahara, 3, and biological daughter Shiloh, 2.

Vivienne’s middle name was reportedly chosen to honor Angelina Jolie's French-Canadian mother, Marcheline Bertrand, who lost a battle with ovarian cancer last year. Knox was the middle of name of Brad Pitt’s maternal grandfather. In the meantime, lawyers for Jolie and Pitt were quick to snap up the Internet domain names KnoxLeon.com and VivienneMarcheline.com.

The offspring of the well-known couple have been made honorary citizens of Nice, France, for the rest of their lives, the city’s mayor declared recently.

The actress expressed her will to give birth in France while at the Cannes Film Festival, saying she made the decision in order to pay homage to the memory of her French-Canadian mother, Marcheline Bertrand, who died last year. Jolie has spent the last two weeks at the French Riviera maternity clinic preparing for the birth. Pitt was spotted visiting Jolie after her hospitalization became public.

Although being born in France is not sufficient to confer citizenship, according to the French Foreign Ministry website, the twins will have the opportunity to obtain French citizenship when they turn 18 provided that France has been their main residence for at least 5 years after the age of 11. Furthermore, they will be permitted to keep both French and American nationalities, with the intention that they will never have to make such a choice.

The Jolie-Pitts acquired a $60 million 1,000-acre estate called Chateau Miraval, located in a tiny village called Brignol in the Var.

The property allegedly has 35 bedrooms, swimming pool, billiards room, indoor pool, gyms, sauna and jacuzzi and a huge banquet hall. The castle is reportedly very intimate, with a driveway three miles long. The place is surrounded by forest on all sides and is close to Aix en Provence.
