Brad to fight Angelina for joint physical custody of kids

Brangelina may be over but Brad Pitt is not rolling over and giving in to Angelina Jolie’s demands for sole physical custody of their six children, according to a report.

Pitt plans to fight for joint physical custody of Maddox, 15, Pax, 12, Zahara, 11, Shiloh, 10, and 8-year-old twins Vivienne and Knox, TMZ reports.

He “doesn’t want to interfere with Angelina’s ability to be a co-parent, but he won’t allow her to thwart him,” a source told the site.

Pitt, 52, who is devastated yet not shocked by Jolie’s demand for a divorce, thinks Jolie is a “great mother” — and he doesn’t want to harm her in the divorce, sources told TMZ.

The actress filed for the split after learning he was cheating on her with his sexy co-star, a source told The Post on Tuesday.

Pitt had been rumored to have been cozying up to his “Allied’’ co-star Marion Cotillard, 40, during the pair’s filming of the World War II drama in London.

TMZ’s sources from Jolie’s camp claim Pitt indulges heavily in weed and alcohol, and also has an anger-management problem that puts their kids at risk.

The site’s Pitt sources, however, claim that allegations that his behavior might endanger the children are completely untrue.
