Angelina Jolie and Brad Pitt\'s Divorce: Everything You Need to Know About Their Shocking Split

Angelina Jolie and Brad Pitt\'s surprising split has shaken Hollywood and fans this week, and allegations of child abuse against Pitt have cast an even more intense spotlight on the couple and their six children.

PEOPLE has confirmed that Pitt is under investigation by the L.A. County Department of Children and Family Services for allegedly getting "verbally abusive" and "physical" with one of his children while on the couple\'s private plane. The case has now also been referred to the FBI, which has jurisdiction because the alleged incident happened while they were flying from France to their home in L.A.

The allegations are all the more shocking because there seemed to be few hints of trouble during the couple\'s 12-year relationship and two-year marriage. They were last seen together in July making celebrating the birthday of their two youngest children, 8-year-old twins Vivienne and Knox, with an intimate family breakfast in Los Angeles. But both actors had been busy with film projects in the months leading up to their breakup.

Jolie asked for physical custody of the couple\'s shared six children – Maddox, Pax, Zahara, Shiloh, Vivienne and Knox. She requested that Pitt, 52, be granted visitation. The actress did not ask for child or spousal support.

Pitt acknowledged the divorce once news of the breakup started circulating on Tuesday.

In a statement released to PEOPLE, Pitt said his focus is on their six children.

"I am very saddened by this, but what matters most now is the well-being of our kids," he said in the statement. "I kindly ask the press to give them the space they deserve during this challenging time."

Jolie also released a statement addressing the divorce through her attorney.

"This decision was made for the health of the family," the statement read. "She will not be commenting at this time, and asks that the family be given their privacy during this difficult time."
