Michael Bublé is now a father of two.
The singer's wife, Argentinian actress Luisana Lopilato, gave birth to their second son, the couple announced on Twitter today.
"And then there were 4," the singer wrote above a photo of the newborn. "Introducing Noah's little brother Elias Bublé @lulopilato #family #blessed #brothers"
Bublé, 40, and Lopilato, 28, were married in 2011. Two years later, they welcomed their eldest, Noah.
"I couldn't have known it was going to be as good as it is," the new father gushed of parenthood a few months later.
Then, in July of last year, he announced that they were expecting yet again. In a video posted to Bublé's Facebook page, Noah pointed to his mother's stomach and said, "Baby!" as Britney Spears' "Oops! I Did It Again" played in the background.
