Sources say that Jennifer Aniston is “really upset” that Angelina Jolie is pregnant again with her ex Brad Pitt’s babies.

According to reports, Jennifer is taking the news of Angelina’s pregnancy extremely badly.

A source close to the actress said: “Jennifer is putting on a brave face, but inside she is really upset. She wasn’t prepared for how she’d feel when she saw the pictures of Angelina and her bump.

“It took her by surprise because it was further proof of just how much Brad has moved on with his life compared to her.”

38-year-old Jennifer still feels resentment towards Angelina because she never had a child with Brad.

The source added to Britain’s Star magazine: “Jennifer is desperate for kids. She can feel her biological clock ticking and is scared that she has left it too late. She keeps saying that she wishes she’d had kids with Brad and that, if she had, maybe things would have worked out differently.

“Splitting up with Brad was the hardest thing Jennifer ever went through, so hopefully she’ll get over this latest hurdle. She’s made of strong stuff.”
