The Bubles, who also have another son, Elias, are excited about the upcoming holidays after going through a "tense time" last year.
"This time last year, the holidays were a tense time for the Buble family," a source close to the family told Entertainment Tonight. "When Noah received a cancer diagnosis, Michael immediately made the decision to step away from his work. It was really a scary time for everyone."
The source confirmed that Noah, who is described as "an energetic little boy," is "doing very well." They added, "Events like this put everything in perspective...There's no doubt Christmas will be extra special at the Buble household this year."
As for the Canadian-born musician, he is apparently feeling like his old self again and is "in a really good head space right now." According to the source, he is really excited about making new music and is already working on multiple projects.
The Grammy winner announced that he will be hosting the 2018 Juno Awards in his hometown of Vancouver, after pulling out of the show last year.
"This is really important to him. It's not only a chance to celebrate Canadian artists, but it's also right in his backyard, since he lives in Vancouver," the source said.
Buble has also been named as the headlining act for the British Summer Time Hyde Park festival next July.
"I can't wait to come over to see my fans in London and play BST Hyde Park for my largest ever UK show! You guys have been patient and I can't thank you enough for all your support," Buble said. "And for those of you that haven't seen me live, well… I just haven't met you yet!"
We're so glad to hear that Noah is doing well! We also can't wait for Buble to return to the scene.
