Michael broke down in tears on Stand Up To Cancer last night on Channel 4. Speaking to James he said his “whole life ended” when Noah was diagnosed with cancer at the age of two.
The youngster underwent chemotherapy and is now in recovery.
However, following the heartbreaking segment, Channel 4 mistakenly tweeted his son had died, prompting an uproar from viewers.
In a tweet which was immediately deleted, they wrote: “Watching Michael Buble talking about the death of his son from cancer is one of the most heartbreaking things we’ve ever watched.
“Sending him and his family so much love for telling their story! Please PLEASE keep donating and help us #StandUpToCancer.”
Those tuning into the Channel 4 special were quick to slam the broadcaster for their error and demanded it be changed.
One Twitter user replied: “Noah is alive and well – get the tweet changed.”
Another added: “His son didn’t die. Come on @Channel4 you need to change this.”
“His son is alive, isn’t he?” a third asked.
Express.co.uk has contacted Channel 4 for comment.
During the Carpool Karaoke segment, he told James: “Well, I mean, it’s so hard to have to acknowledge it because it’s so painful to talk about it.
“But we got the diagnosis, and that was it. My whole life ended.
“He was three. Listen, it was not good. At first, it was… It’s too hard to talk about.”
The 43-year-old continued: “Basically, they said it wasn’t great, and we just took it day by day.
“My sister’s, my wife’s family, they all took their kids out of school, and we just had the best doctors. And God, thank you, Jesus Christ.”
Michael went on to reveal he supported his wife throughout the ordeal but now she “lifts him up”.
“My wife, honestly, when this all started, I became the strength to pull us up and lift us to be positive,” he explained.
“When we got the chemo out, I just, just fell. I fell, and now my wife lifts me up now.”
