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

He finished his statement by saying this:"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 has always been very vocal about his love for being a dad. Recently, the singer opened up about his biggest regret in life.
