Brad Pitt may act like a real sweetheart with his new girlfriend, Angelina Jolie, but Jennifer Aniston's pals are saying the guy's got a heart of stone."Brad made it seem to the world that he wanted kids and Jen didn't," one of Jen's friends reveals to Page Six. "That is a lie. They were trying for kids almost until the end." As far as breaking the news that Angie was expecting, Jen's friend says there was absolutely no courtesy call from Brad to Jen. In fact, Brad had no plans of even telling his ex-wife."Brad wasn't going to bother telling her at all," says the source. "He didn't see why he had to. One of their mutual friends intervened and insisted, so he made his publicist [call Jennifer the day before the news broke]. Nice, huh? Angelina probably has no idea what Brad is really like. She'll find out eventually." Well, if Angie has anything to "find out," she didn't learn it this weekend. Here are some great new photos of the very happy family dining out in Berlin on Saturday.
