The former couple split last week after 12 years together but are said to have been staying in different wings of their 80,000 sq ft Hollywood Hills estate before she filed for divorce from the 'Big Short' star last Monday (19.09.16).

A source close to Brad told Us Weekly magazine: "Angelina basically had her own wing and he had his.

"They began living these separate lives.

"Their arguments progressively became more frequent."

Brad is said to have spoken to some of his pals about the pair's relationship while working on his forthcoming film 'Allied'.

An insider added: "He said they've had rocky moments before, but this is the roughest patch they'd ever been through."

But a source close to the 'Tomb Raider' star said: "She cannot deal with anyone talking about their business."

The pair - who have six children, Maddox, 15, Pax, 12, Zahara, 11, Shiloh, 10, and twins Knox and Vivienne, eight - are said to have signed a pre-nuptial agreement so it seems there shouldn't be too many issues dividing up their combined $400 million fortune.

Between them, the couple are said to own a total of 12 properties, all of which were bought before they married.

Seven houses are Brad's, and two are Angelina's while three others - a New York apartment, a mansion in New Orleans and a vineyard in France - were joint purchases made before they wed, and the pre-nup stipulates how they will be divided.

Angelina has asked for sole physical custody of their children but wants to allow Brad visitation rights, but he wants the care to be shared equally.

It was previously claimed Brad was left "completely devastated" by his divorce.

An insider shared: "He is beside himself and has been crying. He was completely caught off guard and blindsided and had no idea she would do this."
