Bitter Feud: Brad Pitt’s Mom Will 'Never Forgive’ Angelina Jolie For ‘Ruining’ His Life

Brad Pitt has a loved one firmly in his corner as he struggles to finalize his divorce from Angelina Jolie — his devoted mom, Jane!

Pitt, 55, and 43-year-old Jolie may be attempting to negotiate a truce, but the same can’t be said about the angry grandma to the couple’s kids — Maddox, 17; Pax, 14; Zahara, 13; Shiloh, 12; and 10-year-old twins Knox and Vivienne.

“Jane is a tough cookie, and she will never forgive Angelina for what she’s put the family through — especially since they’ve barely seen the kids since the divorce was announced,” an insider exclusively told RadarOnline.com.

“She thinks her son has been treated in a cruel and manipulative way, and she’s not letting this go,” added the source.

As RadarOnline.com reported, before the divorce is all over, Pitt could be out as much as $100 million as he and Jolie work out the final details of their split and custody of the kids.

"Brad’s had to beg his mom not to jump on a plane to confront Angie numerous times, but she wants to look her in the eye and give a piece of her mind,” said the insider. “She blames her for her ruining her son’s life and wants answers.”
