We now know where the real battle lies!

Brad Pitt and Angelina Jolie had a pretty specific prenup, but apparently custody of the kids in the event of a split is the only area that wasn't nailed down before they tied the knot, TMZ reports. As the whole world knows by now, Angie has requested sole physical custody of the couple's six children, so Brad has lawyered up and plans to fight for joint custody.

Aside from the kiddos, it appears dissolving their union isn't going to be that hard. Their prenup is apparently "ironclad" and has specific instructions in regards to dividing up their combined $400 million fortune. The pair share 12 properties together - seven belong to Brad, two belong to Angie, and three they bought together.

The documents are said to make divvying all that up pretty simple, but being in charge of the brood is where it gets messy... good luck BP, you're gonna need it!
