Buble, 37, married Lopilato, 25, in a small civil ceremony in Buenos Aires on March 31, 2011. Days later, the couple tied the knot in front of 300 friends and family in their second set of nuptials. Their third wedding ceremony took place in May 2011 at Vancouver's Pan Pacific Hotel.
"I've said to Luisana a million times I'd love to have kids," Buble told ET Canada in 2011. "But I always say to her when you're ready -- when you feel like you've lived and you've partied and done all the things you want to do. When you've worked your butt off, then tell me."
