Michael Bublé has shared that his three-year-old son, Noah, who was diagnosed with liver cancer, is "progressing well" and thanked God for giving his family "strength" as they battle the disease.
The Canadian star and his Argentine model and actress wife Luisana Lopilato issued an update in a Facebook post on Friday.
"We are so grateful to report that our son Noah has been progressing well during his treatment and the doctors are very optimistic about the future for our little boy. He has been brave throughout and we continue to be inspired by his courage. We thank God for the strength he has given all of us. Our gratitude to his doctors and caretakers cannot be put into words."
They added: "We'd 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."
It is the first official statement since Bublé and Lopilato broke the news of Noah's diagnosis in November. At the time, doctors confirmed that Noah was positive for liver cancer and would have to go through four months of chemotherapy and a surgery to remove the tumor. Thankfully, the little boy was given a 90 percent survival rate.
After the initial diagnosis, the couple said they were "devastated" and that they were giving up work commitments to concentrate on "helping Noah get well".
The "Haven't Met You Yet" singer cancelled appearances including the BBC Music Awards and the Brit Awards, which he was due to host later this month.
Bublé posted on the couple's behalf and asked for support and prayers from everyone, "During this difficult time, we ask that you pray for him and please respect our privacy. We have a long road ahead of us and we hope that with the support of our family, friends, fans around the world and our faith in God, we can win this battle."
The couple has another son, one-year-old Elias.
