Michael Bublé reveals his three-year-old son's cancer diagnosis in heartbreaking post.

In heartbreaking news for the family, Michael Bublé‘s three-year-old son Noah has been diagnosed with cancer.

The singer and his actress wife Luisana Lopilato confirmed the news on Facebook earlier this morning, saying they were ‘devastated’.

“We are devastated about the recent cancer diagnosis of our oldest son Noah who is currently undergoing treatment in the US,” said the statement.

“We have always been very vocal about the importance of family and the love we have for our children. 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.”

There are no details yet about what type of cancer Noah is undergoing treatment for.

The news comes just a week after Bublé’s new album Nobody But Me was released.

The BBC reports that he has a number of scheduled work commitments coming into the Christmas season but that his spokesman said he did not know “anything more at this stage” about whether these engagements would be called off.
