The 27-year-old star has been dating girlfriend Sarah Richards for over two years now but insists they're in no rush to settle down and start a family, reported Now magazine.
"I don't like to jump the gun. We're really good now so you don't want to force anything. She's a dancer so she tours as well - I only end up seeing her a few times a week," he said.
The singer said he loves looking after ex-bandmate Marvin Humes and his wife Rochelle Humes' daughter Alai Mai but isn't sure if he wants children of his own.
