Singer Michael Bublé has shared his shock after his three-year-old son Noah was diagnosed with cancer.
The Grammy winner said on his Facebook page he and wife Luisana Lopilato were "devastated" at the news.
"We are devastated about the recent cancer diagnosis of our oldest son Noah, who is currently undergoing treatment in the US," he wrote.
"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."
Michael Bublé and his wife got married in 2011, and Noah was born in August 2013.
