While the Cannes Festival is primarily about films, this year's seems to have been taken over by Angelina Jolie's personal life.

And if she had hoped to keep things quiet about her pregnancy, she shouldn't have confided in her Kung Fu Panda co-stars. First Jack Black confirmed that she and partner Brad Pitt are expecting twins and now Dustin Hoffman has revealed her due date.

According to the veteran actor she's expected to give birth on August 19.

Jolie told Today: "I'm very happy. Unlike most women, I love being pregnant. [It makes] you feel like more like a woman than you've ever felt. You just feel like everything about your body is there for your baby."

The twins will be the second and third biological offsprings of the celebrity couple following the birth of Shiloh 22 months ago. The family also includes Maddox, 6, Pax, 4 and Zahara, 3.

Speaking about the latter Jolie said, "Our daughter's very proud that she's African," and of Maddox and Pax she added, "And our boys are very proud that they're Asian – they know about their country … down to their food or their flags or their music."
