Michael Bublé moved viewers to tears as he spoke openly about his son’s cancer diagnosis.
While the episode began on an upbeat note, with the duo belting out some of Bublé’s biggest hits, talk became more serious as he admitted his “whole life ended” when he learned his son Noah had liver cancer, aged 3.
“It is so hard to have to acknowledge it,” the Grammy Award-winner said. “Obviously we got his diagnosis and that was it, my whole life ended.
“At first it was just, it is too hard to talk about. They said it wasn’t great so we took it day by day,” an emotional Bublé revealed, before adding: “We had the best doctors.”
“I wasn't OK,” he continued. “When this all started I became the strength to somehow pull us and lift us. When they got it out and chemo was done, I just fell. My wife picks me up now.”
Noah is now in remission. “He is five years old now and I say to him, Spiderman is amazing but they [characters] are fake, they are not real. You are my hero, you are my superhero.”
Bublé’s honesty left Corden, who is a father to three, looking slightly overwhelmed. The pair embraced at the end of the segment.
The episode was only slightly marred by an accidental and highly unfortunate tweet by Channel 4, which wrongly spoke about Noah's "death".
The tweet, which was quickly deleted, read: "Watching Michael Buble talking about the death of his son from Cancer is one of the most heartbreaking things we've ever watched."
As Bublé explained in the Carpool Karaoke segment, Noah is in remission and is "good – he's OK".
Bublé is set to release his new album Love in November. Donations can be made to Stand Up To Cancer here
