Michael Bublé urged fans to cherish their families after being forced to say goodbye to his once again.
The singing star is spending some time away from them all he heads out on his Higher world tour, taking to stage in Barcelona last night.
The Canadian shares his four children, Noah, 9, Elias, 7, Vida, 4, and Cielo, six months, with his Argentine actress wife Luisana Lopilato, 35.
Although the kids are clearly in very good hands, that doesn't make it any easier.
Michael has only spent a few months at home since ending his An Evening with Michael Bublé tour last year.
It is clearly taking its toll on the proud dad as the Feeling Good hitmaker hit the road again.
Michael says that his son's cancer diagnosis has forced him to "lose his alter ego" and concentrate on the things that "really matter".
His world was turned upside down after Noah was diagnosed with hepatoblastoma, a rare type of liver cancer.
That makes life away from home even tougher for the star.
He shared another emotional message, saying his has become used to just “being dad” every day and had enjoyed “every second”, but wanted just a bit more time at home.
Michael shared: “Hey everybody. Just left the house on the way to the airport and it’s really tough leaving my wife and kids.
“It got me to thinking about all you beautiful people who get up and leave and travel far and just spend long days away from your kids.
“I know it’s hard. It sucks and I’m with you.
“I love doing what I do and I love doing it for you and I’m sure when I get to you you’ll bring me out of my funk. I’m on my way to Lisbon.”
Getting more emotional, the 47-year-old added: “I just want to tell you today, go give your kids a hug and a big kiss.
“Squeeze ‘em and enjoy every single second because it goes too fast.
“Thank you for being in my life and letting me show my kids that it’s important to be fulfilled in your job too and that that’s okay.
“I love you guys. See you out there, bye.”
Noah, who is now nine, was just three years old when he was first diagnosed.
Thankfully, the youngster was given the all-clear the following year, but his battle changed the family forever.
Speaking to Red magazine about how his son’s diagnosis affected him, Michael said: “That, of course, changed me in a big way – it changed what mattered to me, it changed how I saw life.
“For most of my life as an entertainer and, especially on stage, I’d become my alter ego.
“Then my wife and I went through this unthinkable thing, and I lost that alter ego.”
