Jill, who recently married Derick Dillard, shared a new photo of her and her sister Jessa Duggar enjoying lunch together in her new home on Monday. In response, many fans believe that Jessa might have gotten engaged to her long time boyfriend Ben Seewald as she is hiding her left hand in the picture along with her sister referring her to "Jessa Seewald" rather than Jessa Duggar.

In the Instagram picture, both Duggar girls are shown smiling for the camera. Jill captioned the picture with: "Lunch with my sweet sis @jessaseewald today! #jessaseewald #jillmdillard #sisterlunch."

However, this is not the first time fans have speculated that Jessa and Ben are engaged. The couple recently took an overseas trip missionary together and posted several cozy-looking photos on social media, causing many to wonder if he had secretly popped the question.

While the couple has been courting for less than a year, they take their courtship very seriously, as they are only allowed to side-hug with kissing or any other physical contact off-limits. The couple has been on dates, but only when a chaperone-usually another family member-- is present.

Meanwhile, the Duggar family recently confirmed some exciting news on their blog: "19 Kids and Counting," will be returning to TLC this fall for its 9th season.

The network hasn't announced the renewal but the blog said that fans can look forward to the premiere of new episodes, including a special focusing on the wedding of Jill Duggar and Derick Dillard.

On the blog, one of the wedding planners named Sierra gave her take on the event which included 1,500 family members and friends.

"At the very beginning, we had talked about it, and I told her, 'If you want help with it, I would love to help you.' And she's like, 'Perfect, yes! Okay!'" Sierra shared on the bog.

Sierra and her assistants had about three months to plan the wedding, and were told as many as 3,000 people could attend.

"I encouraged there to not be a whole lot of Duggar helpers. It's such a special time that if you're not careful, you can forget that it's a special time, and you miss out on the fun joy of being a family when your daughter's getting married. So if we had any questions, we really deferred to the oldest sisters or to Michelle," she said.

"[Jill and Derick] were a dynamic team. I just love watching a bride and groom know what they want and just needing to translate that to a wedding coordinator and then have the wedding coordinator execute it. They really were that awesome team that said, 'Here's what we want. Can we do it?' So we did it."
