"Other than the fame of the people involved, this is like so many other divorces," the source said.
"I am very saddened by this, but what matters most now is the wellbeing of our kids," Pitt said Tuesday in a statement to CNN. "I kindly ask the press to give them the space they deserve during this challenging time."
Jolie's camp is also focused on the children.
"This decision was made for the health of the family," Robert Offer, an attorney for Jolie told CNN in a statement Tuesday. "She will not be commenting at this time, and asks that the family be given their privacy during this difficult time."
