LONDON - Michael Buble has confirmed the devastating news that his eldest son Noah, three, has been diagnosed with cancer.

The Haven't Met You Yet hitmaker took to social media to confirm the devastating news that his son Noah, three, - who he has with his wife Luisana Lopilato - has been diagnosed with the illness and is currently undergoing treatment in the United States.

The tragic news comes not long after the 41-year-old singer - who also has eight-month-old Elias - admitted he didn't realise the "perspective" having a child would give him.

He shared: "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.”
