The beautiful, talented, Canadian-born singer joined James Corden on Karpool Karaoke … and it was everything you would expect.

Singing, surprise saxophonists, coffee orders, driving and conversation.

In this edition of Karpool Karaoke, Buble opened up about his son Noah’s cancer diagnosis.

“We got the diagnosis, and our whole life ended.”

HAPPY SINGING!!
