Angelina Jolie and Brad Pitt welcomed their twins into the world – and into ravenous demand for first photos of the celebrity offspring.

Baby boy Knox Leon and girl Vivienne Marcheline were born one minute apart Saturday night via Cesarean section in a hospital on the French Riviera.

Pitt, 44, “was my assistant,” quipped obstetrician Dr. Michael Sussman, who delivered the twins. “He was very happy . . . the emotion was very strong for him.”

And the babies – who each weighed around 5 pounds – “are doing marvelously well,” Sussman said.

Twins are the best! Ive got the best pair of identical twin girls a dad could ever have in Sophia and Gabriella. If Brad and Angelinas twins are half as great as mine have been, they are in for a real treat! Those twins will be running the Bradalina empire soon enough!
