Paris, July 9 (AP): The windows of Angelina Jolie’s hospital room have been coated with a special material to prevent paparazzi from taking pictures of the pregnant star, the hospital says.

The Lenval hospital in Nice says photos that purport to show Jolie and partner Brad Pitt in their room are fake.

The hospital said the photos — which have been published on the Internet or in magazines — were either manipulated or showed other patients at the hospital.

In a statement, the hospital said it is “totally impossible” to see inside the couple’s room from the outside due to screens covered with a material that lenses cannot see through.

Hospital spokeswoman Nadine Bauer said screens were put on especially for Jolie.

“So any pictures released are either posed fakes set up by paparazzi or they are pictures of other patients,” the hospital said in a statement. “We hope this is clearly understood out of respect for all patients in this clinic.”

Jolie is expecting twins. She has been resting and been monitored by doctors in the seaside hospital in southern France ahead of the birth.

At a brief news conference last week, Jolie’s obstetrician said the actress was doing fine. Dr Michel Sussmann said she would remain in the hospital until the babies are delivered “in the weeks to come”.
