It's been almost two years since Angelina Jolie and Brad Pitt finalized their divorce, but despite rumors that they've both moved on, it seems the wound remains as fresh as ever.
In fact, sources say the mere mention of Brad is enough to make Angie's blood boil -- and she's kept a mental revenge list of the celebs who she feels betrayed her during her divorce.
At the top of that list are George and Amal Clooney, who made no secret of the fact that they sided with Brad during the breakup.
Sources tell London tabloid The Sun that Angelina expected George to be loyal to his buddy Brad, but she was surprised to learn that Amal had been trash-talking her to mutual acquaintances.
Angie apparently suspects that Amal's unkind words have little to do with her affection for Brad, and everything to do with old-fashioned jealousy.
Sources use the word “rivalry” and “hatred” when describing the relationship between Angie and Amal.
And it seems that at the center of the conflict is the humanitarian work that both women are known for.
Yes, even before she and Pitt divorced, Angelina reportedly viewed Amal as competition.
After all, Jolie has devoted much of her adult life to political causes, but she'll always be viewed as an actress first and activist second.
Amal, on the other hand, is a human rights attorney who has never known any other life.
It's difficult to imagine Angelina Jolie feeling threatened, but if anyone could undermine the actress' confidence, it would be Amal.
Angelina has always made it clear that she considers philanthropy to be far more important than celebrity, and in that department, Amal has her beat.
The tension between the two women has been simmering for years, and The Sun claims it boiled over recently when Angie caught wind of some comments Amal had made.
One insider says Amal described Angie's behavior during her divorce as "crazy."
It seems that was all it took to push Jolie over the edge.
Now, the cold war is being fought openly, with the ladies forcing their mutual friends to choose sides.
According to The Sun, Jolie and Clooney have even been competing over decorators, hairdressers, and makeup artists.
The rivalry shows no signs of letting up, as both women feel they deserve to be the queen of the London humanitarian set.
And apparently, Amal isn't the only one making Angie feel insecure about her contributions.
Currently, Brad is dating Neri Oxman, an architect and MIT professor who's widely regarded as one of the top minds in her field.
Again, we don't imagine Angelina is low on self-esteem, but she's up against some pretty remarkable women these days.
