If you’re having a bad day, this will instantly put a smile on your face. Crooner Michael Bublé joined James Corden for an uplifting — and always amusing –special a special  Stand Up To Cancer episode of “Carpool Karaoke.”

It turns serious when host James Corden asks Buble about his 5-year-old son Noah, who was diagnosed with liver cancer at 3.

“It’s so hard to have to acknowledge it because it is so painful to talk about,” Buble began. “We got the diagnosis, and that was it, man. My whole life ended.”

Even though his son’s diagnosis is good, Buble admits he relies on his wife and is still ‘not okay.’
