Canadian singer Michael Popple spoke about his life changing after discovering his son's liver cancer and how his eyes looked different.
"When you pass something like my family, it has to change you," said Buble, who is releasing his new album "Love" (Loew) next month.
Popple had announced in November 2016 that his eldest son Noa, who was then three years old, had cancer and was receiving treatment.
"For me, make things much clearer," he said.
"I do not have time, life is too short to worry about people looking at us or what they say about us," he said.
"I think it is necessary to be free and to find happiness in one form or another, no matter what we have to do, whatever the way and whatever our needs are, to me, I feel that I do not want to call anything or someone to take away my joy."
The 43-year-old singer released his new song "Love You In Meore" a few days ago.
"I know what the word 'grace' means to me, and I think every family treats the situation in a different way as it can," he said.
"I think it's important to do our best and look ahead and try not to sink in the past.
Popple has recently rejected reports in the Daily Mail that he is moving away from the music world.
The new Buble will be released on November 16.
