Michael Bublé shares an update on son Noah's cancer treatment

After announcing in November that their 3-year-old son, Noah Bublé, was undergoing treatment for cancer, Michael Bublé and Luisana Lopilato gave an update on his development 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," the couple said. "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."

The couple - who married in 2011 and are also parents to 13-month-old son Elias - took the opportunity to "thank the thousands of people" who have sent their best wishes to the family since little Noah was diagnosed.

The statement shared by their representative added: "Our gratitude to his doctors and caretakers cannot be put into words. 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."

As well as cancelling all of his planned concerts, Michael, 41, also pulled out of hosting the 2017 BRIT Awards which are being held on February 22.
