Angelina Jolie has FINALLY given birth to twins. Jolie and Pitt welcomed a boy and a girl on Saturday.

“The babies are doing well. The operation went just perfectly,” Dr. Michel Sussmann told PEOPLE Sunday. “Angelina is in very good spirits. Brad Pitt was at her side. He was there and all was well.”

The Jolie Pitt twins names are Knox Leon and Vivienne Marchline. They were delivered by Dr. Michael Sussmann at Fondation Lenval hospital in Nice, France. The little boy, Knox, weighed 5.03 lbs and Vivienne was a solid 5 lbs. Brad stayed by her side as Jolie went through a cesarean section yesterday evening. The names are said to be in honor of their grandparents. Vivienne’s middle name came from Jolie’s mother, Marcheline Bertrand. Knox is in honor of Brad’s grandfather, Hal Knox Hillhouse.

Rumors that Angie was frustrated, grumpy and pushing to “be done” with her pregnancy followed rumors the twins would be born on Tuesday the 15th. Dr. Sussmann assured press hungry reporters that the babies date was pushed forward for “medical reasons.” During the delivery Brad Pitt was with Angelina spent the bulk of the delivery “talking.” Jolie was awake for the section (which is common in case you didn’t know) and very happy. Brad was calm and even cut the babies’ cords.

“He was … perfectly calm, totally determined, very pleased to be at the birth of his children, very moved and very emotional,” said Sussmann.

Asked whether the birth had been a textbook delivery, Sussmann replied, “absolutely no problems.”

Currently everyone is doing fine and plan to stay in the hospital. Apparently in Europe they encourage patients to recover in the hospital longer than the typical 3-4 days after a c-section.
