”Eric has got a lot of friends and we do a lot of things together as a family.
”But you never know with kids if they’re happy being on their own - or, how would he feel if there was another one?
”So look, will it happen? I don’t know. But I would love another kid. I really like being a dad.”
Cowell has lost three stone (19 kilograms) after he overhauled his diet, stopped smoking and cut back on drinking after he broke his back in 2020 when he fell from an electric bike and spent months in rehabilitation.
But, he says, it will still be a challenge to keep up with a young family. He admitted: “When I’m playing football with [Eric], my God, I have to get fit just to play with him.”
”His energy is off the chart, it really, really is.”
Despite changing his lifestyle, Cowell insisted he has had no cosmetic surgery to stay looking younger - aside from a “bit” of Botox.
He added about the recent spate of jokes and speculation he’s had plastic surgery after he was seen sporting a slimmer body and face: “I think it’s hysterical. I mean, it just makes me laugh. I haven’t had a facelift or anything.
”I have had a bit of Botox or whatever, but kind of nothing drastic. So when I hear about this stuff, honestly, it does make me laugh.
“Over the years, people have said that I’ve had everything done. But I don’t google myself, so I genuinely don’t have a clue what everyone is saying about me until we do things like BGT.”
