Michael Buble Son 'Progressing Well' In Cancer Treatment

NEW YORK - Michael Buble says his three-year-old son Noah "has been progressing well during his treatment" for cancer.

The Canadian singer and his wife, Argentine TV actress Luisana Lopilato, say in a statement Friday that "doctors are very optimistic about the future for our little boy." They say Noah has been brave during the battle and they "continue to be inspired by his courage."

The family announced Noah's illness in November, but have not disclosed what kind of cancer he is fighting.

At the time, the couple said they were putting their careers on hold to focus on the toddler's health.

They also have another son, Elias, who turned one last month.

Buble is originally from Burnaby, B.C.
