TORONTO—Canadian crooner Michael Buble and his wife, Luisana Lopilato, are expecting their second baby.

Buble made the announcement Tuesday via a video posted to his  social  media  accounts.

The clip shows their nearly 2-year-old son, Noah, touching his mother’s stomach while Buble, holding the camera, asks: “Who’s that in there?”

Noah replies: “Baby.”

Britney Spears’s “Oops! … I Did It Again” soundtracks the video.

Lopilato, 28, and Buble, 39, married in 2011.
