Angelina Jolie and Brad Pitt Expecting?

Just weeks after news broke that Brad Pitt filed adoption papers to become daddy to Angelina Jolie's kids Maddox and Zahara, rumors are now circulating that Jolie is pregnant with Pitt's baby.
Life & Style magazine is reporting that Jolie's belly has a definite bump and that she had a near fainting spell on the set of her new movie.
Costumers on the Long Island, N.Y. set of Angelina's new flick, The Good Shepherd, noticed that the star's costumes no longer fit around Jolie's stomach.
"Angelina almost fainted," said an insider. "It was a big deal. [Director] Robert De Niro took her aside to make sure she was OK, and they were talking quietly for a few minutes."
Maybe that's why Brad was in a rush to become Maddox and Zahara's daddy?
