Michael Bublé’s son Noah has cancer, the singer confirmed Friday, and he and wife Luisana Lopilato have back-burnered their careers while the 3-year-old fights the disease.

“We are devastated about the recent cancer diagnosis,” the “Haven’t Met You Yet” singer said in a statement on Facebook.

He didn’t specify what type of cancer his son has.

“We have always been very vocal about the importance of family and the love we have for our children,” Bublé said.

“Luisana and I have put our careers on hold in order to devote all our time and attention to helping Noah get well.”

Their 3-year-old is undergoing treatment in the United States, he said.

Bublé and Lopilato’s second child, Elias, was born in January.

Val Kilmer says he has ‘no cancer whatsoever,’ and that Michael Douglas is ‘misinformed’.

Bryan Cranston says he ‘would definitely move’ to Canada if Donald Trump became president.
