Loved by millions, Canadian-born singer Michael Bublé reached worldwide fame back in 2005 with his album It’s Time and his 2007 album Call Me Irresponsible, which reached number one on the Canadian Albums Chart, the UK Albums Chart, the US Billboard 200, and several others.

Over the years, the Grammy Award winner has sold over 75 million records worldwide, but despite the enormous fame he enjoys, he has stayed grounded.

Michael is married to Argentine actress Luisana Lopilato with whom he has four children.

The couple’s son Noah, who will be 9 this year, has gone through an ordeal when he was diagnosed with liver cancer at the age of just 3.

At the time the singer heard the devastating news, he was promoting his ninth studio album Nobody But Me. It was shortly before performing at The One Show on BBC One in London.

“Three minutes before I came on, my wife texted and told me something was wrong,” he said during an interview with U.K.’s Evening Standard in July 2018, and added, “I just died.”

Luckily, Noah is now in remission, but Bublé described the ordeal as “the worst possible thing that you could hear as a parent, and as maybe a human being.”

“I much rather would have it have been me. Many times I wish that it had been,” the musician said and added that the experience made them even stronger as a family and gave them a new outlook at life.

On Noah’s eight birthday, Bublé shared an emotional post on Instagram, writing, “Today my hero turns 8. I’ve never met anyone as brave… I’ve never known anyone as kind or as good-hearted… and I’ll never truly be able to express how proud I am, or how deep and profound Mommy’s and my love is for you. You’ve blessed our lives in every way.”

Along with the touching message, the musician shared two photos of him and Noah over the years.
