Angelina Jolie doctor was nervous at birth

Angelina Jolie and Brad Pitt's doctor has admitted he felt added pressure delivering the couple's twin babies because of their fame.

Oscar-winning actress Jolie gave birth to son Knox Leon and daughter Vivienne Marcheline by Caesarean section in France on Saturday.

When asked on Europe 1 radio whether he was nervous beforehand, Dr Michel Sussmann said, "for sure".

He added: "It's true that there was pressure due to the couple's fame."

'Totally impossible'

Dozens of reporters, cameramen and photographers have been camped outside the Lenval hospital in Nice hoping to catch a glimpse of the babies.

Every effort has been made to protect the actors' privacy.

Last week the hospital issued a statement saying it was "totally impossible" for paparazzi to get photos.

Dr Sussman described Pitt, 44, who was at Jolie's side for the birth, as "perfectly calm" during the operation.

Of Jolie, he said: "She is a patient who was totally obedient, very calm, very kind."

He also said the couple, who also have one biological child together and three adopted children, were "an exemplary father and mother".

Marcheline was the first name of Jolie's mother, also an actress, who died of cancer last year.

It has been reported the pair have sold rights to the first photographs of the twins to an unnamed US magazine and would give the money to charity.

They came to a similar arrangement with Hello! magazine, soon after daughter Shiloh Nouvel was born in 2006.
