BRAD PITT has turned into a groomzilla and his micro-managing every little deet is making ANGIE nuts!!

The “Fight Club” star – who announced his engagement to Angelina Jolie in mid-April – is driving his wife-to-be crazy by obsessing over “every last detail” of their wedding, say sources.

“Brad is determined to throw a party no one will ever forget,” revealed one insider. “He could leave the heavy lifting to a wedding planner, but he’s too detail oriented.”

AS THE ENQUIRER previously reported, the couple, who met and fell in love in 2004 while filming “Mr. & Mrs. Smith,” had a secret beach wedding in the Bahamas in the spring. The plan was to throw a larger wedding party on Aug. 11 at their $70 million French estate, Chateau Miraval, in front of hundreds of guests.

In preparation for the big day, Brad has been making frequent trips between London, where Angie is filming her new movie, and their French home. He’s met with local farmers about supplying produce for the menu and has also conducted taste tests with most of Europe’s top chefs, even asking about where the mushrooms for a particular beef sauce are grown.

Brad is orchestrating everything from the wine list to the wedding outfits for their six kids to the logistics of flying in guests like George Clooney, Johnny Depp, Matt Damon and Clint Eastwood, added the source.

The micromanaging groom-to-be already has the kids going through dry runs of the ceremony.

“Angie just rolls her eyes,” noted the insider. “She doesn’t want any part of it. She told him, ‘Just tell me what time to show up.’”
