Michael Buble "wished he didn't wake up" when he found out about his son's cancer diagnosis.
The 'Haven't Met You Yet' hitmaker and his wife Luisana Lopilato were devastated when they found out that their son Noah, now five, was battling cancer in 2016.
Speaking on Australia's Today Show, he said: "It sucks. It still sucks. What we went through was the worst possible thing that you could hear as a parent, and as maybe a human being. I much rather would have it have been me. Many times I wish that it had been.
"[There were times we] wished we didn't wake up. I've been through a lot. One of the things about going through something that my family has been through is that it gives you great perspective and one of those points of [perspective] is that it really shows you to appreciate the good things."
And now the tot has entered remission, Michael - who also has two-year-old son Elias with Luisana - says everything in their lives has improved.
He added: "I truly thought I would never go back [to music]. I was done. It just seemed completely unimportant compared to what was going on with Noah. Things got very clear for me, very quickly. I live with no fear now. I've been to hell. [Now Noah's better], food never tasted so good, music never sounded so good, my relationship with my family, my faith ... all of it. My wife and I, we got happy, we fell in love again."
