Jolie doctor was 'nervous' before birth of twins

The doctor who delivered Angelina Jolie and Brad Pitt's twin babies was "nervous" before the operation because of his patient's fame.

The actress gave birth to son Knox Leon and daughter Vivienne Marcheline by Caesarian section at the Fondation Lenval hospital in France on Saturday.

Jolie's obstetrician, Dr Michael Sussmann, confessed that he was a little worried before the operation.

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

The pair, who have three adopted children and a biological daughter already, were described as "an exemplary father and mother" by the doctor.

Sussmann adds: "She (Jolie) is a patient who was totally obedient, very calm, very kind."
