The couple, who originally planned to marry this summer, have had to put their plans on hold because of Joe Manganiello's upcoming movie Magic Mike XXL.
"We wanted to get married this summer, but Joe will be busy working and promoting Magic Mike 2," said Sofia Vergara, according to Bang Showbiz.
"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," she added.
Joe Manganiello stars alongside Channing Tatum, Adam Rodriguez and Matt Bomer in the sequel to the 2012 comedy drama, in which they played a band of male strippers.
