Congratulations to Angelina Jolie and Brad Pitt who now join us parents of twins. On Saturday, 12th July, Angelina Jolie, 33, gave birth to a boy, Knox Leon, and a girl, Vivienne Marcheline, by C-section.

Knox and Vivenne both weighed around 5 pounds. Brad Pitt was there during the operation, said the doctor, who delivered the twins at the seaside Lenval hospital in Nice in southern France.

Knox is reportedly Brad’s grandfather’s name, and Marcheline was chosen in honor of Jolie's mother, actress Marcheline Bertrand, who died in January 2007 after a 7 1/2-year battle with cancer.

Jolie and Pitt already have four children: Maddox, 6; Pax, 4; Zahara, 3, and Shiloh, 2.

The first photos of the new twins are expected to fetch millions of dollars, and based on the philanthropic nature of the Jolie-Pitts, the proceeds will no doubt go to a good cause.

The local Nice Matin newspaper referred to the twins as "the most famous babies in the world." The hospital said it had coated the windows of Jolie's room with a special material to prevent paparazzi from taking unauthorized pictures of the star couple.

We wish Angelina and Brad all the best as they experience life now as parents of twins.
