After Angelina Jolie filed for divorce from the 52-year-old actor following two years of marriage, Pitt is asking for privacy in this difficult time.
"I am very saddened by this, but what matters most now is the well-being of our kids," Pitt told People in a statement on Tuesday. "I kindly ask the press to give them the space they deserve during this challenging time."
Court documents obtained by ET show that Jolie filed for divorce on Monday citing irreconcilable differences, and lists the separation date as Sept. 15, 2016. Additionally, the 41-year-old actress is seeking physical custody of their six children -- Maddox, Shiloh, Pax, Zahara, and twins Vivienne and Knox.
ET has reached out to reps for both Jolie and Pitt.
Another source tells ET Pitt has been "carefree in recent months," adding that on a recent trip, "he was going out to lunch, walking around. It’s almost like he didn’t care about anything. He wasn’t your classic, uptight A-list celebrity walking around with a big entourage."
And according to another source, the two also struggled with parenting style for their children.
"Brad has traditional parenting skills -- thinks the kids need structure [like] bed times, consistent schooling," the source says. "Angelina’s parenting style is much more freeform. She’s not into setting boundaries."
