Los Angeles: Actor Brad Pitt reportedly has some “dynamite” audio recordings of Jolie which he may use to prevent her from getting primary custody of their six children. The report of the tapes came days after the DCFS officially closed the child abuse case against Pitt, who was accused of hitting his son Maddox during a September plane fight that led to his and Jolie’s divorce. After eight weeks of investigation, the “Fury” actor was cleared of all allegations, reports aceshowbiz.com. “We believe audio tapes exist of Angelina that would be absolutely dynamite against her if they were to be made public. Nobody wants to play dirty like that – it’s not good for the children – but Angelina and her team seem absolutely hell-bent on trying to discredit Brad in order to stop him getting joint custody,” a source told The Sun newspaper.
