"And then there were 4."

Michael Buble is now a father of two. 

The four-time Grammy Award-winning singer and his wife, Argentinean model-actress Luisana Lopilato, welcomed their second child, baby boy Elias Buble, into the world on Friday.

Buble shared the news with his fans in a Twitter photo following the birth. "And then there were 4. Introducing Noah's little brother Elias Bublé @lulopilato #family #blessed #brothers," he tweeted. 

Lopilato also shared the news on social media with a photo of the couple holding their newborn. "And we are now 4...I present Noah's brother!! Elías Buble!!" she tweeted in Spanish with the hashtags "#family #blessed #brothers."

Lopilato wed Buble in 2011 and gave birth to their first child — son Noah Buble — in August 2013.
