While speaking to Page Six at the Vanity Fair Oscar party, Vergara, 42, said the pair intended to marry in the summer, but was forced to postpone the weeding because Manganiello will be busy promoting his new film Magic Mike XXL.
"We wanted to get married this summer, but Joe will be busy working and promoting Magic Mike 2," she said.
The Modern Family star added, "We want to get married at a time when we can get away and make time for a honeymoon, so the wedding will probably be later this year."
"I would love to get married this summer, but I'm going to be too busy promoting my male stripper movie!" joked Manganiello.
The actors got engaged on Christmas day after dating for five months.
