Brad Pitt and Angelina Jolie are said to have been leading separate lives long before reports of their separation emerged.
The last time they were seen together on the red carpet was at the December 2015 premiere of By the Sea, a film about a couple trying to save their troubled marriage directed by Jolie.
In the months that followed, there were signs that not all was well.
She was consumed with her humanitarian work for the UN, focusing on the lives and treatment of refugees.
Pitt was busy with work, filming his new World War II movie Allied, on location in Europe.
They were last seen publicly over July 4 weekend, when they were spotted shopping in a Los Angeles grocery store. They were also seen at a Jamba Juice, slow-dancing as they waited for their drinks.
According to published reports, they were already sleeping in separate bedrooms, even when they stayed in hotels. They were dealing with serious issues and arguing over how to raise their six children according to reports.
Pitt is said to favor a more traditional, structured approach to parenting while Jolie is more laid back.
It all came to a head earlier in the week when she slapped her husband with divorce papers.
