Michael Buble's 3-yr-old Son Noah is Battling Cancer

Michael Buble and his model wife Luisana Lopilato have announced that their eldest son, Noah, 3, is battling cancer.

Buble, 41, released a statement saying the family had a long road ahead and asked for privacy while they dealt with the diagnosis.

"We are devastated by the recent diagnosis of cancer of our oldest son Noah, who is currently receiving treatment in the United States," he said on Facebook. "We've always talked a lot about the importance of family and the love we have for our children."

"Luisana and I will devote all our time and attention to help Noah to get better, for now suspending our professional activities," he said. "During this difficult time, we ask you to pray for him and please respect our privacy."

It is unclear what type of cancer he has or at what stage.
