The actor duo have children Maddox, 14, Pax, 11, Zahara, 10, Shiloh, nine, and seven-year-old twins Knox and Vivienne.
“Listen, Angie and I were aiming for a dozen children, but we crapped out after six,” Pitt told Daily Telegraph newspaper, reports femalefirst.co.uk.
The 51-year-old actor said that their family life can also be chaotic at times.
“It’s a lot of love, a lot of fighting, a lot of refereeing, a lot of teeth-brushing and spilling… Chaos, total chaos. But so much fun,” he said.
