Elias Bublé, born Jan. 22, 2016, is the middle child and younger son of the Bublé family. Elias doesn't appear on his parents' social media all that often, and they've kept most of the details about their life private.
He does, however, appear to have at least one thing in common with his big brother: a love for superheroes! While Noah's love for Spider-Man is well-documented on Instagram, it looks like Elias prefers Captain America, judging by this sweet snap that Michael shared in honour of Elias's fifth birthday.
