Brad Pitt has "always been a stricter" parent.
Angelina Jolie has filed for divorce from the 'By The Sea' star after reportedly growing increasingly frustrated by his approach to parenting.
A source told People magazine: "Brad has always been stricter. He has wanted the kids to have more structure.
"Brad will get frustrated sometimes and yell at the kids. Angelina always had a more relaxed attitude when it came to the kids. She definitely never yells."
The 41-year-old actress is said to have decided to end her two-year marriage to Brad, 52, after getting "extremely upset" with how Brad was parenting their six children, Maddox, 15, Pax, 12, Zahara, 11, Shiloh, 10, and twins Knox and Vivienne, eight.
Angelina has requested sole physical custody of their children but is seeking joint legal custody and is allowing Brad to have visitation rights.
Meanwhile, Angelina's manager previously revealed the actress decided to file for divorce as she feels it is in "the best interests" of her children.
Her longtime manager Geyer Kosinki said: "Angelina is doing what's best in the interest of taking care of her children. She appreciates everyone's understanding of their need for privacy at this time."
Whilst entertainment attorney Robert Offer added: "Angelina has filed for dissolution of the marriage. This decision was made for the health of the family. She will not be commenting, and asks that the family be given its privacy at this time."
