Michael Bublé is a great artist. He is also a pretty straightforward guy. If something bothers him, be sure he’s not going to hold back. When this mom stopped him in the middle of one of his concerts, he didn’t seem too happy about it. The reason the woman stopped Michael Bublé in the first place was because she wanted her 15-year-old son to get up on the stage and sing a song with him. In the end, Bublé went along with it and invited the boy on stage. What happened next made him give up his place in the center of the stage for a couple of minutes.
