The 41-year-old singer - who has Noah, three, and Elias, eight months, with his wife Luisana Lopilato - wishes he had started a family when he was younger because he didn't realise the "perspective" having a child would give him.

He said: "The only regret that I have in my life is that I took this long to have kids, because I had no idea the perspective it would give me. I had no idea how much I would love being a dad.

"That's it, that's all I care about ... I love them too much probably, if there was such a thing. It's made everything else so insignificant, moments that I was afraid of and moments that would overwhelm me have now become a joy because I've realised how not serious they are compared to what is really important, which is Noah and Eli and that's it."

The 'Haven't Met You Yet' hitmaker altered his drinking and smoking habits after fearing he would "die" whilst doing a physical for his vocal surgery.

Speaking on ITV's Loose Women, he added: "The truth about kind of what happened was, I had this vocal surgery, and during the surgery they made me do a physical where they make you go on a bicycle ... and you have to get your heart rate up to about 168 I think for 8 minutes at a time or something like that and I thought I was going to die. It was horrible.

"I did it and my legs were like all wimpy and shaky and then I looked at my assistant and I got off and I said, 'That's it, no way.' I want to be old. I want to be an old man with these babies and I'm not in the shape I need to be in. And that was simply it. It wasn't like I had this epiphany or [was like], 'I'm never going to drink again.'"
