"And then there were 4. Introducing Noah's little brother Elias Buble," they both wrote on Twitter and Instagram with the hashtags "#family #blessed #brothers."

Michael, 40, and Luisana, 28, are already parents to 2-year-old Noah, and judging by the couple's adorable photos of him on social media, we have no doubt he'll happily fulfill his big brother duties.

Leading up to Elias' birth, the couple shared frequent updates on Luisana's pregnancy with their fans, including a snapshot of the baby's first sonogram and the actress' growing baby bump.

The couple -- who tied the knot in March 2011-- announced they were expecting their second child in July 2015, revealing the news in a video posted to Facebook.
