Joseph Duggar and Kendra Caldwell are engaged and doing great. On a new episode of "Counting On" last night, Joe shared that they plan to get married in the fall. The thing is rumors are flying that they could already be married. It would be very odd for a Duggar couple to get married and not share the news with fans. So why are these rumors flying?

Jeremy Vuolo's new pic has everyone wondering

Jeremy Vuolo went to his Instagram page and shared a picture. In this photo, Jeremy is hanging out with Henry and Spurgeon. It looks like they are having a good time and Jeremy shared that they are at a wedding.

Along with it, he put the caption "Kickin it w/ the wee lads at a wedding! Spurgeon is excited; Henry is confused; both are dressed to impress."

The fans started to go crazy thinking that this might mean that Joseph and Kendra already got married. Obviously, Jinger and Jeremy were at a wedding and then you could tell that Jessa and Ben Seewald were there as well. The thing to remember is that Jeremy was friends with Ben before he started dating Jinger. It isn't surprising at all that they would have a mutual friend who is getting married. It also could have been somewhere that the girls are close to.

Did Joe and Kendra get married?

Besides this one picture of Jeremy, there is no proof at all that Kendra and Joe tied the knot.

There is no reason to think that they really did and the fans are still wondering. It really does look like they will be getting married in the fall at some point. The new season of "Counting On" will start airing next month and that would be the perfect time for their wedding to happen and then end up airing on the show.

Joe and Kendra shared about their engagement not long ago.

They said, "We are so excited to be engaged and look forward to a lifetime together. We are so grateful for how the Lord brought us together, and we look forward to this special time of engagement and to some day serving Christ as man and wife." These two are obviously really excited about their upcoming wedding. They are probably just still in the planning stages of their big day.

Joe will be the first boy to get married in a long time.
