Since the announcement that Michael Buble’s 3-year-old son Noah has been diagnosed with cancer, his mentor, the legendary music producer David Foster is giving Roz Weston an update on the family.

“I think Michael right now is in a huge bubble,” he tells ET Canada. “Everything shuts down around you. You go inside your little bubble.”

Foster is in Toronto to accept the B’nai Brith Canada Award Of Merit for his humanitarian work with the David Foster Foundation, but his thoughts were on Buble, who he has mentored over the years.

“I don’t think he’s looking at social media. I’m sure he feels the love of millions of people,” he adds, saying there has been an outpouring of support from people looking to get in touch with the family and offer words of hope.

“He’s in good shape, he’s got good doctors around him and we will hope and pray for a great outcome, which I believe they will have,” Foster says, adding, “You get in a bubble and nothing else matters. I don’t think he’ll sing again until his child is well. I am certain of it.”

Foster believes Buble has a lot of good karma heading his way thanks to the kindness he puts out into the world.

“He’s done a lot of good for a lot of people and I think this is going to have a great, fantastic ending to it and be a new beginning,” Foster concludes.
