AceShowbiz - Angelina Jolie turned 49 on Tuesday, June 4, and opted for a low-key birthday celebration, surrounded by her children: Maddox, 22, Zahara, 19, Shiloh, 18, Pax, 20, and twins Knox and Vivienne, 15.

We have to go through this.' She's been a really tough assistant. She takes it very, very seriously." Their combined efforts were evident when the pair attended the show's premiere in California, a moment that inspired Jolie to embrace her producer role.

Adding to their shared endeavors, Jolie and Vivienne were recently spotted on May 30 in Los Angeles at the opening night of "Reefer Madness: The Musical," produced by Kristen Bell, a close friend of Jolie.
