Grammy Award-winning Canadian singer Michael Buble has announced his retirement from music after admitting he no longer has the desire for fame following his son's battle with cancer.

Buble has won four Grammys and sold 75 million records. He put his career on hold after finding out that his son Noah, 5, was diagnosed with liver cancer, two years ago. Noah, one of Buble's three children with wife of seven years, Argentinian model and actor Luisana Lopilato, is now in remission.
