According to FemaleFirst, Jolie does not like George Clooney, who is one of Brad Pitt’s friends.
A source told Life and Style Weekly, "Angie is not particularly close to George, so she didn’t see why she had to be there. She asked Brad if he minded going alone, but Brad says it wasn’t really a question. And it was fine with him."
Jolie fears that Clooney distracts Pitt from his parental responsibilities.
The source addded, "Angie doesn’t get along with any of Brad’s friends. When they are back in Los Angeles she discourages him from going on boys’ nights out."
According to FemaleFirst, Clooney feels the same way about Jolie.
