The couple are proud parents to three boys Kingston, 8, Zuma, 5, and Apollo, 3 months, reported Us magazine.
"We have so many kids now, no matter what, it's rock solid. Apollo is 3 months old so he's pretty chilled out. We're very proud of him. He's a great kid (but) he'll be naughty soon enough," he said.
When asked just how naughty his other kids are, the 48-year-old singer said, "Oh, they're terrible! So naughty!"
But the Bush frontman does not mind his wild boys.
