India, June 13 -- Days after reports of former actor-couple Brad Pitt and Angelina Jolie's daughter, Shiloh, dropping her father's surname, a new report states that Brad, too, has severed ties with her and son, Pax. As per the Daily Mail, sources close to Brad (61) say that he believes these relationships are now irreparable. This follows recent images of Pax leaving Chateau Marmont in Los Angeles (USA) in an allegedly intoxicated state. The source said, "Brad has zero concerns with what Pax does or doesn't do. His actions reflect who he is." The actor sees his bond with the 21-year-old as "unfixable". Although Brad has distanced himself from Shiloh and Pax, insiders suggest he still hopes to reconcile with his other four children.
