Michael Bublé Said His 'Whole World Ended' After Son’s Cancer Diagnosis

Michael Bublé has opened up about his son Noah’s cancer diagnosis in a moving Carpool Karaoke with James Corden.

The Canadian singer teared up when he recalled the moment his then three-year-old child was diagnosed with a rare type of liver cancer.

"It's so hard to acknowledge it because it's so painful to talk about," Bublé said. "We got the diagnosis and that was it, man, my whole life ended."

Bublé said he and his wife Luisana Lopilato "just took it day by day" after hearing the news -- and were surrounded by a strong support network of relatives.

"My sisters, my mum, my dad, my parents, my wife’s family. They all pulled their kids out of school, we all moved and we lived at CHLA (Children's Hospital Los Angeles). And we just had the best doctors."

Bublé said that while he remained strong throughout Noah's chemotherapy, he "fell apart" when his son was given the all clear.

"I became the strength to somehow pull us and lift us and to be positive and when they got it out and the chemo was done and they said 'We did it, it's great, we're good, he's okay' I fell. I just fell. My wife picks me up now."

The "Haven't Met You Yet" singer then made an emotional plea to the Carpool Karaoke audience to pick up the phone and donate to cancer research charities.

"There’s nothing better in the whole world when you give that way, the universe gives right back to you," he said.

"There’s hope and treatments and medicines that haven’t been discovered and will be discovered because of you. You think you’re one person that can’t change [it] but all of us can completely make that huge difference.”
