Baby Bublé on the way

Michael Bublé has something new to sing about: he's becoming a father.

In an online video posted Thursday by the YouTube account of Bublé's wife, Luisana Lopilato, a sonogram of the baby with the words "Mini Bublé!!!" is shown. The 20-second video ends up with words: "We're having a baby Bublé!!!!"

The 37-year-old Canadian singer and his 25-year-old Argentine actress-wife were married in 2011. The couple met in 2009 during a South American concert tour.

A representative for Bublé confirmed that the couple are expecting.

Buble is a Grammy-winning pop singer who has sold millions of albums, including "Crazy Love" and 2011's "Christmas." Lopilato made her name as a model and in Argentine sitcoms and soap operas.
