Michael Buble revealed on Friday that his 3-year-old son, Noah, has been diagnosed with cancer.

The 41-year-old Canadian singer and his wife, Luisana Lopilato, shared the sad news on Buble's Facebook page. "We are devastated about the recent cancer diagnosis of our oldest son Noah who is currently undergoing treatment in the U.S.," the statement reads. "We have always been very vocal about the importance of family and the love we have for our children."

The message goes on to say that Buble and Lopilato, a 29-year-old Argentine actress and model, will be taking a break from the entertainment industry to ensure the well-being of their child. "Luisana and I have put our careers on hold in order to devote all our time and attention to helping Noah get well," the statement continues. "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.”

ET's Jennifer Peros recently spoke exclusively with Buble -- who just released his seventh studio album, Nobody But Me -- about the love he has for his sons, and how fatherhood has changed him. "I love them more than I'll ever love anything, or anyone in the whole universe," Buble said of Noah and his 9-month-old son, Elias. "I think it gave me perspective on life that I think I very badly needed. It's hard to be able to quantify that level of love."

"I didn't know that level of love existed. But it makes me better at everything," he added. "It allows me to pull more emotion and be more honest and to be in the moment."

Buble also opened up about the fears that come with being a parent. "You're scared all the time because you love them so much that you can't ever, ever think of a world without them," he told ET. "You try not to even think about it."
