Michael Bublé has opened up about his son’s battle with cancer in a special Stand Up To Cancer Carpool Karaoke interview with late-night host James Corden.

In 2016, then three-year-old Noah was diagnosed with liver cancer.

“It’s so hard to have to acknowledge it and talk about it,” an emotional Bublé said. “Obviously we got the diagnosis and that was it man, my whole life ended.” 

Bublé revealed his entire family, including his wife’s family, all made the decision to move to Childrens Hospital Los Angeles.

In 2017, the artist released a statement to Us Weekly which shared Noah had been doing well during treatment and doctors were optimistic about his future.

Though little Noah, now five-years-old, beat the disease Bublé said the emotional fallout has left him “not okay”. 

“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.”

“It’s funny, he’s five-years-old now and I say to him – because he loves Spider-Man – ‘Spider-Man’s amazing, and Superman’s amazing, but they’re fake, they’re not real. You’re my superhero, my real superhero.”

Bublé then urged all viewers watching at home to donate to the Stand Up To Cancer organisation.

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

(Fair warning, this interview starts off all cheery and then it breaks your heart.)

Bublé’s new album, Love, is set to be released on November 16.
