Three years after her split with ex-hubby Brad Pitt, Jennifer Aniston is still whining to anyone who’ll listen. Not only can she not get over the fact that Angelina Jolie stole him away, but she’s also jealous that they keep popping out babies.

OK! Magazine says:

“It’s been three years since they split,” a friend says. “But she’s still so far from getting over him, it’s tragic.”

And on Feb. 23, when Jen, Brad and Angelina Jolie, will all take part in hosting a charity event at the Beverly Hills Hotel, the tension in the room will most certainly be palpable.

Aniston is gearing up for the moment she’ll have to say hello to Angelina or, as she chooses to put it, “that person who ruined my life.”

Making the matter more stressful for Jen, who turned 39 on Feb. 11, is that she’s being constantly bombarded with images of a glowing, pregnant Angelina. “Jen is desperate for kids,” says a source. “She can feel her biological clock ticking and must be scared that she’s left it too late. She keeps saying that she wishes she had kids with Brad and that, if she had, maybe things would be different.”

She should have given Brad babies when she had the chance. The glory days are over - time to move on!
