Apparently Jolie hired a private investigator to spy on the pair while they where filming in London.
A source has said:
“Angelina was aggressive and very negative towards Marion when they met earlier this year on the set of Allied.
“Angelina insisted on being there to keep a watch on Brad and he was mortified by how he treated Marion who is happily married and a very professional woman.
Sound slike Angelina turned a bit syco and went a bit mad but if she thought something was going on between them then who can blame her?!
