‘The kids would run riot. The Pitts have a huge backyard and they would go sledding in winter and have campfires in the summer.’

The source also claimed that ‘as far as [they] know’ Jane and William had not been visited by their grandchildren since 2016, and cited tensions between the matriarch and Angelina as the cause.

‘Jane is a Christian conservative who once slammed gay marriage, while Angelina is a liberal who has dated women, so it was never a recipe for a friendship. But no one ever thought it would turn out like this,’ they claimed.

MailOnline has contacted Angelina’s representatives, a spokesperson for Brad has declined to comment.

In a filing in Los Angeles Superior Court, Jolie argued that Judge John W. Ouderkirk should be taken off the divorce case that she filed in 2016 because he was too late and not forthcoming enough about other cases he was hired for involving Pitt attorney Anne C. Kiley.

It says that during the Jolie-Pitt proceedings Ouderkirk has ‘failed to disclose the cases that demonstrated the current, ongoing, repeat-customer relationship between the judge and Responden’s counsel.’

It goes on to say that Pitt’s attorney ‘actively advocated for Judge Ouderkirk’s financial interests in moving – over the opposing party’s opposition – to have his appointment (and his ability to continue to receive fees) extended in a high profile case.’

An email to Kiley and Pitt’s lead attorney Lance Spiegel seeking comment was not immediately returned.

A new twist: On Monday Angelina (pictured 2018) asked that the private judge overseeing her divorce from Brad Pitt be disqualified from the case because of insufficient disclosures.
