Angelina Jolie is reportedly desperate to give birth naturally. The 'Wanted' actress - who is expecting twins with partner Brad Pitt - was said to be disappointed when she had to have a Caesarean section with her first biological daughter Shiloh, and is determined not to undergo the procedure again.

A source said: "She prepared for a natural childbirth for Shiloh and was very disappointed when her doctors told her she would have to undergo a Caesarean section. She is praying everything will go her way and she will be able to enjoy a natural birth. "

She has been told to expect the babies early, and that is why she and Brad have gone to France - so they are ready for their babies whenever they decide to make their appearance." Angelina denied reports she had given birth to twin daughters last week, but is expected to welcome the new arrivals into the world before the end of the month.
