Fans discovered that Vuolo, who is the pastor at Grace Community Church in Laredo, Texas, included in his bio that he and Jinger, 24, "are expecting their first child in July of 2018."
But in an embarrassing mistake, the biography also reads that Jinger and Jeremy wed in November 2017! They actually wed the year before, on Nov. 5, 2016, and presumably they will soon fix the error.
The wedding date mix-up is bizarre given the shotgun wedding scandal that has embroiled Jinger's sister, Joy Anna Duggar, soon after she married husband Austin Forsyth. Joy Anna is heavily pregnant and fans charged she broke Duggar family strict courtship standards.
But Jinger has had no such supposed sex before marriage issue, having celebrated her first anniversary with Jeremy in Nov. 2017.
The couple recently announced their pregnancy to US Weekly, saying, "The past 14 months have been the best of our lives as we have had the wonderful privilege of beginning our journey through life together in marriage. We both looked forward to the joys of marriage but neither one of us fully understood just how amazing the start of this journey would be. Truly, the Lord's mercies are new every morning! Now, the journey has taken an exciting turn: We are expecting our first child!"
"We are praising God for this beautiful gift and ask that you join us in praying for a safe and healthy pregnancy," the Vuolos added.
Jeremy, a former soccer player, now serves as a full-time pastor at the small church in Laredo.
He surprised Jinger -- who had to move away from her large extended Duggar family in Arkansas -- with a romantic birthday dinner in December in which she appeared to be hiding her baby bump on Instagram. Soon after that, they made their baby announcement.
