'19 Kids & Counting' John David Married? Jessa And Jill's Brother Following In Sister's Footsteps?

Is another Duggar family member about to be married off? Well, it certainly looks that way: 19 Kids & Counting stars Jessa Duggar and sister Jill Duggar may have both just recently said "I do" to husbands Ben Seewald and Derick Dillard, but John David may be the next member of the strict Christian family to take the leap into married life.

According to Radar Online, the older brother to Jessa and Jill, has been hanging out with a mystery girl lately, and has even been taking her to some of his family's get-togethers.

And it looks like the proof is in the pudding as a close friend of the Duggar family posted picture to his Instagram account, which shows John David hanging out with the mysterious brunette at both a book signing and a family dinner.

In the pictures, the possible girlfriend is wearing a yellow top as she sits next to John at dinner, and a white sweater while at the book signing.

The Instagram user, realizing they created a lot of speculation by posting the images, have since taken them down and made their account private.

But if the girl isn't John's new girlfriend, it seems he isn't going to have trouble in that department.

During a recent episode of the family's TLC series, John David jokingly said at his sister's wedding that he was going to start taking applications for a bride, and it looks like people took the joke seriously, as they started sending in applications.

John told People magazine that while it was a joke, his family did receive some submissions.

"It was a joke," the reality star explained. "But I hear that we started receiving applications like crazy. I don't know how many have come in and I haven't looked at any, but I hear there are a lot."
