Jennifer Aniston tried to call ex-husband Brad Pitt to congratulate him on the birth of his daughter with Angelina Jolie.

A source quoted in Grazia magazine revealed: "she thought it was the right thing to do. But she couldn't get her call accepted. Jen thinks Angelina has changed Brad and made him as insensitive and uncaring as she is. As far as Jen is concerned, not taking her phone call was the last straw. She had intended to be civilized and be nice but Brad and Angelina don't seem to want to do that."

As fametastic.co.uk writes, Jolie and Pitt are set to return to Los Angeles from Namibia within the next few days.
