Michael Buble 'Devastated' Over Son Noah's Cancer Diagnosis

The singer took to Facebook with a heartfelt post.

— -- Singer Michael Bublé took to Facebook Friday morning to confirm his 3-year-old son Noah has cancer. He did not say what type.

"We are devastated about the recent cancer diagnosis of our oldest son Noah who is currently undergoing treatment in the US," the Grammy winner wrote in a statement.

He continued, "We have always been very vocal about the importance of family and the love we have for our children."

Bublé, 41, and his wife Luisana are also parents to Elias, whom they welcomed in January. The duo tied the knot in 2011 and welcomed Noah two years later.

"Luisana and I have put our careers on hold in order to devote all our time and attention to helping Noah get well," Bublé said. "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.”
