Famous singer returns to stage after son's battle with cancer

The singer became very emotional and thanked the crowd for their love and support.

Singer Micheal Buble returned to stage after two long years, as his 4-year-old battled with liver cancer, according to The Mirror. The singer chose to perform at BST in London's Hyde Park, as his comeback performance.

Despite heavy rain at the park, Buble performed hits like Feeling Good, Just Haven't Met You Yet, and Home. After playing a few songs, the Canadian singer opened up to the crowd.

He revealed that he was scared to sing after his two-year long hiatus and was worried if he would be able to perform any more, but the cheering audience gave him strength. Read more about Michael Buble on our Twitter account @amomama_usa.

He also thanked the audience for their love and support, not just for that evening, but for the past two years. Nearing the end of the evening, Buble brought on Noah, his 4-year-old, on stage.

The singer got visibly emotional at this point, as he proudly spoke about how Noah enjoyed the movie The Greatest Showman, and how he was forced to watch it multiple times because of that.

The 42-year-old singer has not been in the limelight since the diagnosis. He used his social media account only twice in the two years to update about Noah's treatment.

However, he spoke about his family enduring through this crisis when he received an award in Ottawa earlier this year.

Both he and his wife, Luisana Lopilato, had canceled all their work commitments after the devastating diagnosis. The duo wanted to spend as much time with their son as they could.

The couple has another son, one-year-old Elias, who was also present at the concert. Buble recently confirmed that they are expecting a third child, a girl; and that she was due in August.
