Brad Pitt fears that Angelina Jolie has reached 'breaking point,' according to a US tabloid.

It's claimed that “months of nonstop traveling, bickering with Jennifer Aniston, and tending to the constant needs of the six kids” is taking it's toll on the fragile actress.

"Brad is scared to death that she's going to crash and burn," an 'insider' tells The National Enquirer.

"Angelina is usually super-organized but in the past two weeks, she has lost it. She's stressed, unorganized and more forgetful."

The tabloid cites Angelina's tearful appearance - or what the Enquirer refers to as her "emotional breakdown" - at the UK press conference for new movie Changeling as evidence that the star is meltdown-bound.
