According to TMZ's sources, Jolie got "fed up" with Brad smoking pot (and maybe drinking), as the drug use combined with what she's apparently calling "an anger problem" that led to a situation she felt was unsafe for their kids.
The sources tell TMZ it's not about another woman, it's just a matter of how Pitt was parenting the children. Jolie's entertainment attorney, Robert Offer, told TMZ that she decided to file for divorce "for the health of the family."
Jolie's manager, Geyer Kosinski, also gave an exclusive statement to E! News, which simply said, "Angelina will always do what's in the best interest of taking care of her family. She appreciates everyone's understanding of their need for privacy at this time."
