2. Brad Pitt may have cheated.
Do you remember the old saying “If they’ll cheat with you, they’ll cheat on you?” A source said Angelina hired a private eye and found out that Pitt had hooked up with Allied co-star Marion Cotillard for months during filming. That was the final straw.
3. They mixed business with pleasure.
Pitt and Jolie co-starred in By the Sea which focused on a broken relationship between an unhappy couple. This may have been a case of art imitating life.
4. They have different lifestyles.
Jolie and Pitt have different priorities. It’s said that Jolie looks for fulfillment outside of Tinseltown and in humanitarian efforts, while Pitt prefers being Hollywood’s golden boy.
5. Their schedules are hectic.

10. Gwen Stefani’s divorce
Gwen Stefani, Jolie’s best girlfriend, finally split from Gavin Rossdale after years of rumored trouble in their marriage. That in turn may have given Jolie enough courage to break out on her own and fly solo without Pitt by her side.
