More details about Brad and Angie's troubled marriage emerge

Los Angeles - Angelina Jolie and Brad Pitt reportedly have a lot of "bad blood" between them. 

The Maleficent actress, who filed for a divorce from the 52-year-old actor last month, is reportedly "seething" with the Fury actor because something he allegedly did during their 12- year relationship has left her ''very pissed off'', according to US Weekly. 

The 41-year-old actress - who has children Maddox, 15, Pax, 12, Zahara, 11, Shiloh, 10, and eight-year-old twins Vivienne and Knox with Brad - is believed to have signed her and the Hollywood hunk up for family counselling to cope with their divorce, although this is not a plan to rekindle their marriage. 

However, Angelina isn't the only one to be angered by the situation as Brad - who married the UN Goodwill Ambassador and Special Envoy two years ago - has also been left feeling frustrated since his spouse filed for a divorce but is willing to "work through everything". 

A source told the publication: "Brad just wants to work through everything and get to a place where there can have some certainty about what's going on. The kids are the only thing he's hanging on to."

Although Angelina - who has recently been granted full custody of her children in a temporary custody deal with Brad, which will see her have full physical custody of her children for three weeks until 20 October when new recommendations can be settled - reportedly has ''so much stuff'' on her that Brad could use against her, he won't bring any of it up in the court battle because he doesn't want to ''play dirty''. 

The source added: "There is so much stuff on Angelina but Brad just doesn't want to go there. He told his team he doesn't want to play dirty."

Meanwhile, it has been reported the Department of Children and Family Services has advised the couple on possible things to change in the hope they can "resolve things" without the complications of going to court. 

The source explained: "The hope is that this period of time will lead them to being able to resolve things without the involvement of the courts."
