Vergara, 40, and Loeb, 37, got engaged in July 2011 on a trip to Rivera Maya, Mexico for the actress's birthday.
Earlier this month, Vergara had said that no wedding plans had been made yet, but that when the time came, the celebration would be big.
"If I'm going to do something, it's going to have to be a big event. I just had my 40th birthday in Mexico. I had more than 100 people."
