Canadian crooner Michael Bublé sealed his "Crazy Love" for Argentine actress Luisana Loreley Lopilato de la Torre by marrying her in a civil ceremony in Buenos Aires, Argentina, on Thursday.
Bublé, 35, wore a gray suit for the ceremony, while the bride donned a violet dress with silver high heels. The pair kissed for the cameras and posed for fans gathered outside, and the bride threw a bouquet of purple orchids into the crowd.
The couple got engaged in 2009
, when the singer proposed in front of Lopilato's family in her native Argentina.
But the party still isn't over. The pair will reportedly hold a bigger ceremony this weekend with 300 guests celebrating at a mansion outside Buenos Aires.
The pop star first met his Argentine TV star wife after one of his concerts in Buenos Aires in November 2008. "They met at a party the record company threw for him after his show in Buenos Aires," a friend of the singer's told PEOPLE shortly after the engagement. "The head of the label wanted to introduce Michael to Argentina's most famous actress. When he met her, he said it was love at first sight."
And, the friend says, those closest to them couldn't be happier. Their families have met "several times and are all very happy about this union," says the friend. The two have even worked together: She appears in the video of his hit single, "Haven't Met You Yet."
Bublé won the Grammy last month for traditional pop vocal album.
