Brad Pitt Says Being A Father Has Toughened Him Up

Brad Pitt is "impervious to poo, snot, urine and vomit." The "Ocean's Thirteen" actor - who raises six children with partner Angelina Jolie - revealed becoming a father has toughened him up and ensured he can cope with anything.

He said: "I'm tough as nails. I'm impervious to poo, snot, urine, vomit. You can't get me. You cannot break me down."

Brad, 44, also revealed he and Angelina don't often take their brood shopping because it is such a struggle to get everyone organized.

He added to TV talk show host Oprah Winfrey in an interview which will air Wednesday: "We don't go to the mall. It's like a half-an-hour just to get everyone buckled in and make sure they've got their snacks, and Zahara has got a blanket and Shiloh's got her silky."

"Angelina is militant about it. She's right on top of it. Thank God, because I'm always forgetting something!"

Meanwhile, Angelina has revealed she only breastfed her four-month-old twins Knox Leon and Vivienne Marcheline for the first three months because she struggled to cope with feeding the babies simultaneously.

She said: "You think, 'Ah, if anybody can do that, I can do that.' There's this football hold - it's a lot harder than it looks in the books. I did that a few times. I would take turns. It just takes a long time."
