The actor said that his mega-brood causes him the 'biggest pain' he's ever experienced!
Brad, 48, has six children with Angelina Jolie - Maddox and Zahara whom they adopted,
Shiloh Nouvel, who is their biological child, Pax Thien, who they adopted from a Vietnamese orphanage, and biological twins, Knox Léon and Vivienne Marcheline.
With the kids ranging in age from four to 10, Brad admits that, as much as he loves it 'and can't recommend it any more highly', sleep is 'non-existent'.
"It's chaos at times, but there's such joy in the house," he told Celebs on Sunday.
Brad also reveals that growing up, he was envious of his pals who had large families, having only two siblings himself:
"I had a friend who had a big family when I was a kid," he said, "I just loved the chaos around the breakfast table and the fighting and the ribbing."
"I just decided then if I was ever going to do it, that's the way I was going to do it."
Looks like he fulfilled that ambition then!
Could YOU cope with six kids (if you had the money)?
