Brad Pitt spilled on fatherhood at the Venice Film Festival on Sunday.

"It's the most fun I have ever had and also the biggest pain in the ass I have ever experienced."

"(But) I love it and I can't recommend it any more highly."

When asked by Italian state TV if he and partner Angelina Jolie were ready for a fifth child, Pitt replied: "Yeah, we're ready."

Pitt, 43, added that having a family has also helped his career, PEOPLE reports.

"It makes me much more efficient," he says, "because that's the main focus. It makes me feel when I do have time to work, I really do have to focus because there is a really short window to get something done. I am quite pleased by it all."
