It’s a beautiful day! Michael Bublé and his wife, Luisana Lopilato, welcomed their second child, a boy, on Friday, January 22. The singer, 40, announced the happy news via Instagram.

“And then there were 4. Introducing Noah's little brother Elias Bublé #family #blessed #brothers,” the Canadian crooner wrote alongside an Instagram photo of himself with Lopilato and their newborn son.

The Grammy-winning artist and the Argentine model, 28, are already parents of 2-year-old son Noah.

"I love everything about the kid," Bublé told Us Weekly about his firstborn in 2014. "Instead of being nervous like I used to at events, I actually sit beforehand and say, 'You're Noah's dad first, and all of this other stuff is just icing on the cake.'"

Bublé and Lopilato married in March 2011.
