The celebrity footballer and underpants salesman told The Sun he felt blessed to already have four kids, but "it would be great" to have one or two more!
He and Victoria have sons Brooklyn, 13, Romeo, nine, and seven-year-old Cruz, as well as 10-month-old daughter Harper - but he said: "We are very lucky to have four healthy children. It would be great if we had one or two more although two might scare Victoria! But maybe one more, you never know.
"We're enjoying the kids at the moment, so we'll continue to do that. If we decide in the future to have two more, who knows."
He also gave an insight into how Harper is growing up as the little sister of three big brothers.
"With three boys, obviously there's a lot of energy in our house," he said.
"They are constantly on the go from the moment they wake up to the moment they sleep.
"Harper is totally different. She is relaxed, she is feminine.
"I think that was the biggest thing for me. It's silly, but everything about her is feminine and to have a little girl, it still amazes me every time I change her: I'm like: 'Oh my God, we've got a little girl'."
He also said the family will one day return to live in the UK.
"At the end of the day, I always miss London - just having pie and mash with my Mum or Dad and visiting my Nan," he said.
