Brad Pitt has been caught by Angelina Jolie

When Angelina entered the bedroom of 8-month-old twins, Knox and Vivienne. Brad was on the bed, rubbing the back of their beautiful young nanny! Angie got so mad she slapped Brad and fired the girl on the spot! "She completely flipped out. She got right in Brad's face, screaming at the top of her lungs, and told the nanny to get out of her house and never come back!" the source says. After a huge fight, Brad Pitt and Angelina Jolie are now sleeping apart. "Angie is still very angry over the nanny thing," an insider tells Star. "Right now, the separate bedrooms arrangement seems to be the best thing for them. Brad doesn't want to face her cold fury every night."

Brad is so unhappy about sleeping solo that he's even taken to "camping out" with the kids in sleeping bags inside little tents in their rooms. "He tells them it's because Mommy's working late again, but it's really because she banned him from their bedroom," the insider adds. What's up Brad, if l had Angelina every night, that would be more than enough!
