Bauer said the 33-year-old actress will almost certainly remain in the hospital until she gives birth. She said Jolie was admitted so she could be kept under normal surveillance - and is not expected to give birth immediately.
Bauer said Jolie was admitted recently but wouldn't say exactly when.
"There's no urgency. It's been planned for a long time," she said. "She's very well. Everything is fine."
Jolie has said the babies are due in August. She and partner Brad Pitt have four children: Maddox, 6; Pax, 4; Zahara, 3; and Shiloh, 2.
The Brangelina clan has been settling into a new home in the south of France. They recently moved into the Miraval Estate villa in the French hamlet of Correns, in the Provence region.
