Canadian crooner Michael Buble says his three-year-old son Noah is "progressing well" as he undergoes treatment for cancer.
"The doctors are very optimistic about the future for our little boy," Buble and his wife Argentine actress Luisana Lopilato said in a statement Friday.
"He has been brave throughout and we continue to be inspired by his courage."
The statement comes a few days after it was announced that Buble cancelled his gig as host of the Brit Awards on Feb. 22 in London.
Buble is still slated to host the Juno Awards on April 2 in Ottawa.
Buble and Lopilato announced in November that they would put their careers on hold to devote their attention to helping Noah get well. They also have another son, Elias, who turned two in January.
On Friday, they thanked Noah's medical team and fans for their support.
"Our gratitude to his doctors and caretakers cannot be put into words. We'd also like to thank the thousands of people that have sent their prayers and good wishes to us. As we continue this journey, we are greatly comforted by your support and love."
