At present, Angelina Jolie has a winning edge over Brad Pitt, as she is trying to get "sole custody" of their six children. However, Brad Pitt has a set of "bombshell audio tapes" that he will fire on her if she does not permit him to have joint custody, say reports Friday.

They are embarrassing and hurtful tapes that might stymie Angelina's plans of taking over her children's sole custody.

"We believe audio tapes exist of Angelina that would be absolutely dynamite against her if they were to be made public," an inside source said. 

It wouldn't really be a decent salvo to throw, yet Brad Pitt is sure to use every ammunition in his care so that he doesn't lose his children - Maddox, 15, Pax, 12, Zahara,11, Shiloh, 10, and twins Knox and Vivienne, both 8.

"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," the source said.

Pitt would reportedly would like to arrive at a private compromise on the custody arrangements rather than enter a court battle. "Brad has made it obvious that he wants to come to a mature arrangement and stop throwing dirt at each other," the source said. However, if he doesn't get his way, he would probably not play the gentleman. 

A puzzling point for many is - how does Pitt believe that he will not get custody of his children even after getting cleared of abuse allegations by the LA County Department of Children and Family Services?

Anyway, one party that would definitely be interested in the tapes is the Angelina bashers among the media and the curious public. They perhaps would be quite happy to learn about them - so they might even invite the hurling of the tape scandal on her.
