Michael Buble is singing a happy tune today after marrying Luisana Lopilato in a civil wedding ceremony in Buenos Aires yesterday. The bride wore a purple pleated mini dress with sheer tulle trim while the Grammy-winning singer donned a dark grey suit paired with a silver tie. The happy couple posed for fans before Luisana tossed her orchid bouquet into the crowd. The two are planning two more ceremonies this month – one in Buenos Aires for the bride’s family and another in Vancouver for the groom’s family.
