Just days after revealing his 3-year-old son Noah’s devastating cancer diagnosis, Michael Bublé has officially canceled his performance at the BBC Music Awards on Dec. 12.

The event, scheduled to take place at London’s ExCel auditorium, and will feature appearances by Lukas Graham, Emeli Sandé and the Kaiser Chiefs.

Bublé’s cancellation was announced by DJ Steve Wright on his BBC Radio 2 show. BBC Music director Bob Shennan added his warm thoughts. “We send Michael and his family our very best wishes.”

In the initial announcement posted to his Facebook page last Friday, the 41-year-old Canadian crooner said that he and wife Luisana Lopilato would pause their professional ventures.

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

Kind words for the young family have flooded in from across the globe. Actress Shannen Doherty, herself battling the disease, offered encouragement.

“Just trust in your doctors,” she told Entertainment Tonight. “Make sure you have amazing doctors, a great team and know that organizations like the American Cancer Society, Stand Up to Cancer are doing so much good for cancer. And [there is] so much research that we have much better chances now. Stay positive. That positivity, that outlook on life that you can get through something, it actually does get you through.”

Bublé’s sister Brandee also shared an inspiring message by posting a sweet picture on Instagram.

“And now these three remain: faith, hope, & love. But the greatest of these is love,” reads the chalkboard writing on the photo — a biblical quote from 1 Corinthians 13:13.

“And we’ve got a lot … ” the children’s book author captioned the sweet message, adding a heart emoji.
