Michael Buble's wife is expecting their first child.

The 'Home' singer's spouse, Argentinian model Luisana Lopilato, announced the happy news on her official website earlier today (24.01.13), under the heading ''Mike and I have big news for you.''

The 25-year-old beauty then linked visitors to a homemade clip on video sharing site YouTube, showing off the first sonogram image of the couple's unborn child before switching to a cute picture of the loved up mother and father to be kissing.

The video ended with the message: ''We're having a baby Buble!''

Canadian singer Michael, 37, met married the Argentine beauty in 2008, before getting engaged to her in 2009.

The smitten crooner penned his hit song 'Haven't Met You Yet' for his wife-to-be, who appeared in the music video.

The pair wed in April 2011 in two ceremonies, one in Buenos Aires and one in his home town of Vancouver in Canada. Instead of going on honeymoon, they opted to carry out charity work in Africa for underprivileged children.
