Police reports said thieves forced their way through the 35-year-old Buble's front door, cut off the alarm system and covered security cameras before taking objects and money, El Universal reported.
The couple spoke with police just hours after their ceremony in the Argentine capital.
"I will not let this ruin the happiest day of my life," Lopilato said.
Lopilato said through a message on Twitter the thieves did not take anything of much value from the house.
Sources said the burglars tried to break into Lopilato's parents' house first but were unsuccessful.
