The two actors are set to say "I do" at The Breakers Palm Beach hotel in Palm Beach, Florida on Sunday, and guests, including Sofia's uncle Hernando Vergara and Modern Family co-stars Jesse Tyler Ferguson and Ariel Winter started making their way down there today.
Rooms start at more than $600 at the famed hotel, which is completely booked this weekend. The guest list is expected to be 350 to 400 names long and Joe, an avid Pittsburgh Steelers fan, invited some players from his home team, which has a bye week this weekend.
While the resort is known for holding romantic seaside ceremonies, these nuptials are not likely to take place outside, as there is a 90 percent chance of rain.
Sofia explained to CoverGirl that it is not customary for a Colombian wedding to have bridesmaids in a YouTube video, but she does have a special role for her niece Claudia in lieu of that.
"She's going to be dressed in a beautiful soft dress, because she's going to help me holding the flower arrangement, and she's going to be there fixing my dress," Sofia said.
