Singer Buble's anguish after son diagnosed with cancer
Singer Michael Buble's three-year-old son, Noah, has been diagnosed with cancer.
The Canadian musician wrote on his Facebook page that he and his wife, Luisana Lopilato, were "devastated" at the diagnosis.
The message read: "We are devastated about the recent cancer diagnosis of our oldest son Noah, who is currently undergoing treatment in the US.
"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 we hope that with the support of family, friends and fans around the world, we will win this battle, God willing."
According to reports, the boy was diagnosed after he and his mother travelled to the US because of health concerns.
The type of cancer he has has not been revealed.
Buble and Argentine model and actress Lopilato (29) are also parents to nine-month-old son Elias.
During a recent appearance on ITV's Loose Women, 41-year-old Buble praised his children for giving him "perspective" and said that he was unaware how much he would enjoy being a father.
He added: "The only regret that I have in my life is that I took this long to have kids, because I had no idea the perspective that it would give me.
"I had no idea how much I would love being a dad. That's it, that's all I care about... I love them too much, probably, if there was such a thing.
"It's made everything else so insignificant. Moments that I was afraid of and moments that would overwhelm me have now become a joy because I've realised how not serious they are compared to what is really important, which is Noah and Eli and that's it."
Buble was recently announced as the host of next year's Brit Awards.
He has also made several public appearances recently, including on an episode of Desert Island Discs and his own Buble At The BBC showcase, where he told host Claudia Winkleman he "just didn't know that level of love existed".
He said of his sons: "I just love them so much that part of loving them so much is not giving them everything they want, and that is a tough thing for me."
The news comes as Celebrity chef Jean-Christophe Novelli revealed the "devastating news" that his newborn baby boy had been diagnosed with neuroblastoma cancer.
Eight-week-old Valentino is undergoing hospital treatment after Novelli and his fiancee, Michelle, found a lump on their son's neck last week.
