Michael Bublé is one proud dad.
The singer has shared a gorgeous photo of his youngest son, Elias, all dressed up in a superhero costume, to mark his milestone birthday.
"You are my pride and joy, a man after my own heart ❤️ Happy 5th Birthday, Elias Bublé!," he captioned the snap.
It's not the first time the father-of-three has referred to his kids as 'superheroes'.
In April last year, Bublé and his wife, Luisana Lopilato, were hosting a live Instagram show, when eldest son, Noah decided to crash the video.
The six-year-old didn't stick around for the entirety of the video, coming in and out of frame as his famous parents answered questions from fans.
At one point, the couple opened up about his 'devastating' liver cancer diagnosis in 2016 when he was three, describing their eldest son as their "biggest inspiration".
"You know what he wants to be when he grows up? Not an actor, not a singer. He wants to swim with sharks," Bublé said. "So, this is our superhero. We have two other superheroes, but this boy… you know what? He is the biggest inspiration for us."
Lopilato and Bublé are notoriously private about their family life - rarely sharing photos of their adorable tribe on social media.
The couple have three children together, Noah, Elias, and one-year old Vida.
