The 42-year-old actress revealed as much in an interview with Extra at PaleyFest on Saturday. Vergara previously told Page Six she and the actor are too busy to wed this summer, and Manganiello recently said he and the star are planning for the fall.
"I don't know, how can something be postponed when it has never been set?" Vergara asked of the couple's much-rumored wedding date. "It's really funny. It's always a lot of fun for girls to plan the wedding."
