Looks like the drama isn’t over for Brad Pitt and Angelina Jolie when it comes to his ex-wife, Jennifer Aniston!

A source exclusively tells In Touch that the pair was at odds after the mother-of-six, 41, learned that her husband, 52, was in communication with his pregnant ex, 47, following the death of her mother, Nancy Dow.

“It was their first moment in months without the kids or staff around,” a source tells In Touch. “Angie thought a good one-on-one conversation would enable them to finally catch up on their lives. Then, Brad casually mentioned that he’d reached out to Jen to send his sympathy after her mom passed away in May. He didn’t think it was a big deal.”

Needless to say, his wife didn’t feel the same way.
