Angelina Jolie and Brad Pitt are divorcing after two years of marriage. It was announced Tuesday that the longtime couple was calling it quits, and apparently the split has something to do with how Pitt parents their children.

TMZ  reported that Jolie filed divorce documents Monday citing irreconcilable differences. However, sources shared a little more information about the shocking breakup telling the outlet that a fight over their kids triggered them throwing in the towel on their marriage.

“Sources connected with the couple tell us … Angelina’s decision to file has to do with the way Brad was parenting the children … she was extremely upset with his methods,” TMZ wrote. “Her decision was solely over Brad’s interaction with their children.”

Pitt and Jolie, who wed in August 2014 after 10 years of dating, have six children together: Vivienne Marcheline Jolie-Pitt, Knox Leon Jolie-Pitt, Zahara Marley Jolie-Pitt, Maddox Jolie-Pitt, Shiloh Nouvel Jolie-Pitt and Pax Thien Jolie-Pitt.

Even though it’s not clear why Jolie was supposedly so upset over Pitt’s parenting skills, the former lovebirds have done several interviews in the past gushing over their family. Check out eight of Pitt and Jolie’s quotes on their children below:

Brad Pitt On The Joys Of Having Kids: “Everyone talks about the joy of having kids — blah, blah, blah. But I never knew how much I could love something until I looked in the faces of my children,” he told The Telegraph in November 2015.

Angelina Jolie On Her Husband’s Parenting Style: “He loves being a father and that’s one thing I’m most proud of about him. With a large family, you need that support,” the “Mr. and Mrs. Smith” actress told The Mirror in March 2014. “Brad is a wonderful teacher and guide, for the boys in particular. He likes to plan things and proceed in a very deliberate and methodical way. He is much cooler and calmer. … I can be more impulsive and outspoken.”

Brad Pitt On Discipline: “I am [the disciplinarian] with the boys. Girls do no wrong, so I don’t have to be,” he said during an interview with The Telegraph in November 2015. “I feel like my job is to show ‘em around, help them find what they want to do with their life, put as many things in front of them, and pull them back when they get out of line, so they know who they are.”

Angelina Jolie On Motherhood Being Tiring: “You get spoiled on a film set and in some ways it’s easier to be working long hours on a movie than taking care of a large family just because you do get very tired at the end of the day,” she told Hello! Magazine in November 2010. “I felt that way especially after the twins were born because the demands on your time are so great.”

Brad Pitt On Making Mistakes: “Not [like I’m] a horrible parent, but I’ve certainly made mistakes and had to make up for it,” he said to People magazine in May 2011.

Angelina Jolie On Being A Dorky Parent: “We wake up, we make breakfast. In our domestic life, we’re Mom and Dad. And often we’re dorky Mom and Dad, which the kids find ridiculous,” she told Wall Street Journal in November 2015.

Brad Pitt On Loving His Kids: “I worry about them all the time,” the actor told Psychologies  magazine in October 2014. “That’s the emotional bond and responsibility that sweeps over you when you have a family to look after. I care about them more than I care about myself. You see past yourself and become more generous and giving, and wanting only the best for your family.”

Angelina Jolie On Pitt Being A Strict Parent: “I used to be the tougher parent but since the birth of the twins, Brad’s had to play bad cop more often,” she explained to Britain’s OK! Magazine in March 2012. “It also depends on which of the children we’re talking about. … I think I’m a little closer to the girls, maybe, but he’s always making them laugh.”
