"During this difficult time, we ask that you pray for him and please respect our privacy," the statement continued. "We have a long road ahead of us and we hope that with the support of our family, friends, fans around the world and our faith in God, we can win this battle."
The "Home" crooner and his wife share two sons, Noah and Elias, and Bublé previously told E! News that fatherhood as completely changed his life for the better. "I think being a dad gives you perspective. I think really being a parent is a massive blessing," he told us. "It's allowed me to understand deeply that what I do for a living—creating music and art and getting to be a part of a fragrance or a movie—is my job. It isn't what defines me. What defines me is I'm Noah and Eli's dad."
Even though Bublé's career often takes him on the road, he said his favorite place is at home with his family. "When I'm nervous and I'm insecure and I'm scared of challenging myself or leaving my comfort zone, [fatherhood] just gives me context and allows me to understand what's important," he added.
Our thoughts and prayers go out to the Bublé family.
