Michael Bublé might be a huge star, but he clearly hasn't forgotten where he came from. When a mom asks if her son can come onstage and do a duet, Bublé doesn't seem to hesitate. His readiness to give this young kid a chance might stem from how he got his start as a singer. When Michael Bublé was still a teenager, he snuck into a nightclub to enter a singing competition. His performance blew everyone away and he was announced the winner. However, he was later disqualified for being underage. Still, he made such an impression that the competition organizer signed him and put him on the path to stardom. It seems he hasn't forgotten those humble beginnings, years later.
