Simon Cowell would like to have another child.
The 58-year-old music mogul admitted he felt he'd left it too late to start a family before his girlfriend Lauren Silverman fell pregnant with their son Eric, now four, and the youngster brings so much joy to his life, he'd be happy to expand his brood further.
Asked if he'd like another child, he told the Daily Mirror newspaper: "If you'd have asked five years ago would I have one now, I'd be thinking, 'I might have left it a bit late'.
"But once you've had one you think, how could you imagine him not being here? So when it happens, it happens.
"I never thought I could think this way, but you just go, it would be unthinkable to think he wasn't here.
"I can't really think about life before Eric, so yes I would consider another child."
And Simon insists there is nothing "complicated" about fatherhood.
He added: "I was laughing with someone last night about Eric. I said, it's not as complicated as you think, they get you and you get them."
One Direction star Louis Tomlinson, 26, turned to his mentor for support when his ex-girlfriend Briana Jungwirth got pregnant with their son Freddie, now two, and the 'America's Got Talent' judge promised him being a father would be the "best thing" that would ever happen to him.
He recalled: "Louis called me when it was happening, and I said, 'Look, I've been there, right, and all I can tell you is you embrace it and you deal with it as a guy, and it will be the best thing that's ever happened to you.'
"It's as simple as that. You have no idea what to expect."
Simon likes to bring Eric to work with him on 'The X Factor' or his other talent shows and finds it useful to study his reactions.
He explained: "I watch Eric when we make the show sometimes. If he switches off I'm thinking, 'Maybe that is boring.' I'm being serious."
