Michael Bublé Says His Son's Cancer Diagnosis 'Rocked My World': 'Sledgehammer to My Reality'

The singer shares his four kids — Noah, Elias, Vida and Cielo — with wife Luisana Lopilato

Michael Bublé is opening up about his son's cancer diagnosis.

While appearing on an episode of the Diary of a CEO podcast, the singer, 48, was asked by host Steven Bartlett about a time when he felt like his priorities in life shifted, prompting him to open up about his 10-year-old son Noah's liver cancer diagnosis.

"My son's cancer diagnosis rocked my world," Bublé began. "It pulled the curtain from over my eyes."

"And that was a sledgehammer to my reality. And I will never be carefree and that's okay. It is a privilege for me to exist and that pain, the fear, the suffering that comes with those sort of things is I guess it's part of that beautiful, this life."

Bublé then clarified his statements, sharing that he thinks he was going through a crisis before his son got sick.

"I don't think I had my priorities straight. I mean my family was always my love but I don't think I was a terrible guy but dude, it was blinders. Career. Ambition. How do I become the baddest, biggest, best. You know, more ego, more power, more money," he shared.

"And on Halloween, however many years ago that was, dude it's like life was lived with a curtain in front of me. Like a filter. And the moment that they said this is what's happening, that reality hit me."

"Filter gone. And I mean, in a moment. In one moment. Gone. And I went, 'Ok. This is it. This is life. This is it, this is what's important.'"

The "Haven't Met You Yet" singer shares his four kids — Noah, Elias, 7, Vida, 5, and Cielo, 15 months — with wife Luisana Lopilato.

Bublé's son Noah was diagnosed with liver cancer in 2016 at age 3. He's been in remission since 2017.

During an interview with Australia's Today Show last October, Bublé described the ordeal as "the worst possible thing that you could hear as a parent, and as maybe a human being," adding, "I much rather would have it have been me. Many times I wish that it had been."

In 2021, the musician talked with PEOPLE about how his son Noah's battle with liver cancer changed him, saying, "I live a much deeper life now."

"I don't wish that kind of pain upon any human being, but I do feel that when you've truly suffered, when you've truly felt fear and loss, it allows you to live a deeper life," said Bublé. "Once you've felt those things, you are able, in context, to truly feel joy, gratitude and happiness."

"My grandpa used to say, 'Today's curse is tomorrow's blessing,' " he continued. "Even though for some of us who have lost so much these last few years, whether it's our jobs or our loved ones, it doesn't all come with negative connotations. There's always a silver lining to that cloud."
