Things pretty much couldn't be nastier.

Angelina Jolie's lawyers have filed new legal documents accusing Brad Pitt of not paying adequate child support for their six children, and she's requesting that the judge put a retroactive order in place to get the money owed, TMZ reports.

"[Pitt] has a duty to pay child support. As of present, [Pitt] has paid no meaningful child support since separation. Given the informal arrangements around the payment of the children’s expenses have not been regularly sustained by [Pitt] for over a year and a half, [Jolie] intends to file an RFO [request for court order] for the establishment of a retroactive child support order," the papers read.

The Oscar winner also wants the courts to sign off on the divorce so she can be "single" again, even if they haven't reached a mutual custody agreement yet.

It sounds like Angie is out for blood!

"Angie’s big issue continues to be sharing joint custody with Brad. She can’t see past her anger for Brad that he is on his way to getting joint custody," a source told Us Weekly.

Who could have predicted this is how their epic love story would end? Well, maybe Jennifer Aniston did...
