Michael Bublé and his wife have welcomed their second child, the "Haven’t Met You Yet" crooner announced via Twitter Friday.

The singer posted a picture of himself, wife and actress Luisana Lopilato, and baby Elias shortly after the baby’s birth. “And then there were 4. Introducing Noah’s little brother Elias Bublé," Bublé wrote in the caption. The couple are already parents to two-year-old Noah.

The duo originally announced the pregnancy on his Facebook page back in July 2015. The post included a video with Noah, who was asked “Who’s in there?” as he touched his mother’s belly and said, “baby!” The announcement came shortly after Noah had been hospitalized following an accident at their home in Argentina, the actress’ native country. Fortunately, Noah was released shortly after and sent home, with the family reuniting and spending some time in Bublé’s native Canada.

However, the duo is not far from done! Bublé told People Magazine that the duo wanted to have around five kids. “If we can’t do it naturally, we’ll do it another way -- we’ll adopt," he said.

Bublé is also confirmed last year he is working on his ninth studio album, although no release date has been set currently.
