“They are so tired of people asking about their wedding, and they are tired with dealing with all of the wedding details,” a source said of Sofia, 43, and Joe's upcoming nuptials.

“They are just so ready to do it and be done with the wedding. They literally joke about counting the days to the wedding. They are excited but they are both really stressed out about it right now," the insider added to Us Weekly.

Sofia and Joe first began dating in July 2014 and the True Blood actor popped the question just six months later in December 2014 while the two were on vacation in Hawaii. This will be the first marriage for Joe and the second for Sofia, who was previously married to her high school sweetheart, Joe Gonzalez — with whom she has a 23-year-old son, Manolo — from 1991 to 1993.
