Michael Bublé has reportedly canceled his 2017 BRIT Awards hosting duties to be with his three-year-old son Noah, who was diagnosed with cancer last year.

The annual ceremony, which takes place on February 22 in London, has yet to announce a new host.

An insider revealed to The Sun newspaper: “It was a difficult call but Michael has decided to pull out of hosting the BRIT Awards. Out of respect for Michael the producers gave him as much time as he needed to make the decision, which they completely understood.

He would have put a unique stamp on the night so it’s a real shame, but at the moment his priority is his family. They are exploring other options now about who will take his place and a number of people have thrown their hat in the ring. No matter who they pick it will be an incredible night.”

The 41-year-old singer – who has an additional child with wife Luisana Lopilato – abruptly canceled numerous commitments to dedicate more time to his son.

In fact, his friend David Foster had recently revealed that he refuses to perform until the cancer-stricken child is back to normal.

He shared: “He will not sing again until his child is well, I’m certain of it. Right now he’s in a huge bubble, as you would expect.

When this happens, everything shuts down around you. You go inside your little bubble and I don’t think he’s looking at social media. I’m sure he feels the love from millions of people.”

His Noah is undergoing a four-month chemotherapy treatment and the chances of survival are said to be at 90 per cent.
