Angie's Vodoo Rituals Before Battling Brad!

‘The maids are a little scared!’

FLAKY Angelina Jolie locks herself in a spooky “chamber of horrors” for hours before emerging to wage war against ex Brad Pitt in their ugly custody battle, sources say!

“Angie’s deeply rooted in the spiritual side of things, with a bit of magic and voodoo thrown in,” an insider snitches to GLOBE.

“She’s got a meditation room with an altar, candles, incense and all kinds of paraphernalia, including bowls of potpourri, jars of powders and bottles of elixirs.”

Adds the snitch: “Sometimes she’s up at 4 a.m. and she’ll sit still for hours in candlelight until the sun comes up. No one bothers her in this chamber of horrors because they’re still asleep and the maids are a little scared.
