Brad Pitt has been photographed leaving the hospital in Nice
Actress Angelina Jolie's doctor has said her twins may take a few more weeks to arrive.
Dr Michel Sussmann said at a news conference that the 32-year-old was doing fine and would give birth "in the weeks to come."
Dr Sussmann stressed that the actress had checked into the hospital to be closely monitored, not because of any medical emergency.
Jolie checked into the Lenval Hospital in Nice, France, earlier this week.
She is expected to remain there until she gives birth.
Asked when the actress is expected to have her twins, Dr Sussmann replied: "I can't give you a date. Let's say the birth will happen in the weeks to come."
"Mrs Angelina Jolie and her husband, Brad Pitt, told me to tell you that she is doing absolutely fine," said the doctor, apparently unaware that the stars are not married.
"Her hospitalisation at this stage in her pregnancy is totally normal for a patient who had a Cesarean during her first pregnancy," he added.
Jolie confirmed she was expecting twins in May
The doctor denied some media reports that the whole fifth floor of the hospital had been given over to the Jolie-Pitts, saying they had reserved just four rooms for them and their bodyguards.
"She is a patient like any other - she is very well and she is okay," he said, but would not reveal the sex of the babies.
Jolie already has one daughter with actor Brad Pitt - Shiloh Nouvel Jolie-Pitt, who was born in Namibia in 2006.
The couple have also adopted three more children - Cambodian-born son Maddox, daughter Zahara from Ethiopia and Pax, from Vietnam.
Jolie confirmed she was expecting twins at the Cannes Film Festival in May after her Kung Fu Panda co-star Jack Black accidentally referred to them in an interview.
She has since said the babies are due in August.
