Brad Pitt opens up about his marriage to Angelina Jolie-Pitt and life with their children in a new interview, describing his life as "chaos, total chaos." The 51-year-old actor, now starring in the new film "By The Sea" with his wife, reveals that things in his home can be a bit hectic but says it's "so much fun."

“There’s a lot of love, a lot of fighting, a lot of refereeing; a lot of teeth-brushing and spilling,” Pitt tells the Telegraph of London about his large brood. “Chaos, total chaos. But so much fun.” 

He continues, “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.” 

Pitt and the 40-year-old actress are parents to six children: three biological -- Shiloh, 9, and twins Knox and Vivienne, 7, and three adopted -- Maddox, 14, Pax, 11 and Zahara, 10.

During the interview, Pitt admits he and Jolie-Pitt initially aimed to have a dozen children but they "crapped out after six."

The "World War Z" star also dishes on how he disciplines his kids, saying "girls do no wrong."

"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," he explains.

As previously reported, Jolie-Pitt also opened up about her family in a separate interview with the Telegraph earlier this month.

“Brad and I have problems like any other couple," she shared. "We have days when we drive each other absolutely mad, but the problems in [‘By The Sea’] aren’t our specific problems.”
