Our favorite Canadian crooner Michael Bublé married Argentinian actress Luisana Lopilato in Buenos Aires over the weekend. The couple first enjoyed a civil ceremony, and later celebrated in grandeur with 300 guests at a private mansion. The groom, 35, sang his hit “Haven’t Met You Yet” to his new bride at the reception in a DSquared2 suit, a song he originally wrote for her in 2009, and they had their first dance to Dean Martin’s “Everybody Loves Somebody.” The bride, 23, wore three dresses for her multiple affairs: a purple dress for the civil ceremony, a Sylvie Burstin gown (shown), and a Marchesa design. The couple had been engaged since 2009. Click through to see inside the Bublé-Lopilato wedding!
