Brad Pitt has moved out after a furious bust-up with Angelina Jolie – and friends fear the couple is heading for an ugly legal battle that will tear their family apart!

The ENQUIRER has also learned Brad plans to ask for custody of ALL six children if their split ends up in court, where a judge may have to work out who gets what of their $200 million fortune.

Insiders say the couple’s fairytale romance imploded when Brad, 45, confronted Angelina over not devoting enough time to him, while he’s been caring for their children – Maddox, 7, Pax, 5, Zahara, 4, Shiloh, 2, and 8-month-old twins Knox and Vivienne.

While Angie’s been filming Salt all over NYC, Brad’s been stuck playing Mr. Mom with the Brangie Brood.

"It ended up with a big shouting match," an insider told The ENQUIRER.

 "They may end up splitting for good, and if it comes to that, Brad is going to ask for custody of all the children," the insider said.

And dividing up the couple’s tangled assets will be a legal minefield, friends say.
