Michael Bublé is a changed man.
The Canadian singer has opened up about why he decided to lead a healthier life, which involves drinking and smoking less.
Michael, 41, opened up about his lifestyle changes
"I had this vocal surgery, and during the surgery they made me do a physical where they make you go on a bicycle," Michael, 41, told Loose Women.
"You have to get your heart rate up to about 168 I think for eight 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 like 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.'"
The singer has two adorable sons with his wife Luisana
Michael is happily married to his stunning Argentinean wife. Speaking about the couple's two children, he admitted: "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."
