Michael Buble and wife expecting baby

Michael Buble has a baby on the way.

The 37-year-old Canadian singer and his wife, Argentinean actress Luisana Lopilato, 25, are expecting their first child.

The couple, who tied the knot in 2011, revealed the news in an online video clip on Thursday, showing a picture of an ultrasound.

The 22-second clip, set to Buble's hit "Haven't Met You Yet," features the on-screen text: "Mike, LU and ... mini Buble!!! We're having a baby Buble!"

They had two wedding ceremonies when they wed in 2011 -- one in Buenos Aires and another in Vancouver. Buble dedicated "Haven't Met You Yet" to Lopilato, who appears in the accompanying music video. The song is featured on Buble's 2009 Grammy-winning album, "Crazy Love."

Buble put out a holiday compilation, titled "Christmas," in 2011 and expects to release a new studio album this year.
