Brad Pitt’s plans to marry pregnant Angelina Jolie have come to a screeching halt after the couple got into a screaming match over details of the ceremony, Star has learned exclusively.

Brad wants a big wedding in New Orleans, the town he has adopted in a bid to help get it back on its feet after Hurricane Katrina, while Angie says she would like a small, intimate ceremony in France.

And when Brad told the mom-of-four — with two more on the way — that he had asked his mother, Jane, to help with the arrangements, Angie hit the roof, sources say.

“They ended up going to separate bedrooms and slamming doors. Angelina was so frustrated, she was crying,” one friend of the couple says.

Angie’s main problem with Jane Pitt is that she’s still close to Brad’s ex, Jennifer Aniston, and even suggested she should be on the guest list. “Brad tried to reassure Angie that she wouldn’t show up,” says the source. “Still Angie’s furious. Anytime Jen’s name is mentioned, she gets jealous.”
