"Our gratitude to his doctors and caretakers cannot be put into words," the joint statement continued. "We'd also like to thank the thousands of people that have sent their prayers and good wishes to us. As we continue this journey, we are greatly comforted by your support and love."

Bublé and Lopilato announced in November that their son was diagnosed with cancer.

"We are devastated about the recent cancer diagnosis of our oldest son Noah who is currently undergoing treatment in the US. We have always been very vocal about the importance of family and the love we have for our children," the statement said. "Luisana and I have put our careers on hold in order to devote all our time and attention to helping Noah get well. At this difficult time, we ask only for your prayers and respect for our privacy. We have a long journey in front of us and hope that with the support of family, friends and fans around the world, we will win this battle, God willing."
