Michael Bublé is expecting second child with wife Luisana Lopilato

Here comes baby Bublé No. 2: Michael Bublé and his wife are expecting their second child.

The golden-voiced crooner and wife Luisana Lopilato both announced the pregnancy on social media with an assist from their firstborn.

In a short video clip posted by the couple, someone off-camera, presumably Bublé, asks their son Noah "who's that in there?" as Lopilato lies on the ground baring her belly. Noah walks over to his mom and says "baby," pointing to the Argentinian actress' abdomen.

Bublé's rep declined to say how far along Lopilato is in her pregnancy.

The news comes just a week after the 22-month-old was hospitalized in Buenos Aires after a domestic scalding incident. The little guy looked happy and healthy in the video, just as Bublé said he was when he returned home last week.

This will be the second child for the pair, who wed in the Argentine capital in 2011. They followed up those nuptials with a second ceremony in Bublé's native Canada.

The Grammy Award winner, 39, and Lopilato, 28, also announced that the model-singer was pregnant with their first baby Bublé back in January 2013 with a sweet YouTube video.

The 22-second clip started with text saying "Mike, LU and Mini Bublé!!!" set to his song "I Just Haven't Met You Yet." It then displayed images from his wife's live ultrasound.
