Burnaby-raised crooner Michael Bublé is not one of those celebrities who hides from the media.

So it shouldn't come as a big surprise that he took to social media today to announce that his wife Luisana Lopilato gave birth to a baby boy.

His name is Elias.

He's the younger brother of Noah, 2, who was spotted on a Facebook video touching his mom's stomach last year and asking, "Who's that in there?"

Now, Noah has his answer.

Last June, Bublé told People magazine that he would love to have three, four, or five kids. And if it doesn't happen naturally, then they'll consider adopting children.
