Aniston 'upset' by Jolie baby rumours

Jennifer Aniston is upset by rumours that Angelina Jolie is pregnant, reports claim.

The actress is said to have responded badly to speculation that Jolie is expecting twins with partner Brad Pitt.

A source told Star magazine: "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."

Aniston, who split with Pitt in 2005 after five years of marriage, reportedly regrets that they did not have a child.

The source added: "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."

It was recently reported that Pitt, Aniston and Jolie will co-host Hollywood's pre-Oscars party later this month.
