"Yeah, we're ready," said Brad Pitt, when asked if they were ready for more kids.

During an interview with an Italian TV station during the Venice Film Festival, Pitt said, “Having kids is the most fun I've had and also the biggest pain ... I've ever experienced. I love it and can't recommend it any more highly -- although sleep is nonexistent."

So, Shiloh, Maddox, Pax and Zahara may soon have a new bro or sis!
