Fans believed Jana joining Instagram meant that she was finally in a relationship because Duggar family rules usually mandate Jim Bob and Michelle's children aren't allowed to create their own public profiles until they are dating someone long-term.
Plus, handsome pal Lawson Bates of Bringing Up Bates left a flirty comment on Jana's post!
However, on Thursday, January 10, Jessa, 26, weighed in.
First, she shared a photo of Jana and Jinger Duggar's daughter, Felicity. "I love this pic of @janamduggar and our little niece!" she wrote.
When fans responded with chatter about Jana possibly being in courtship, Jessa wrote, "She's not in a relationship." She added playfully, "But if anyone is interested, please send all applications to me. I will check them out thoroughly."
Jessa, who just announced her third pregnancy with husband Ben Seewald, also reaffirmed that it was just a coincidence that only courting and married Duggars had Instagram accounts, explaining that it was "definitely not a prerequisite."
As RadarOnline.com previously reported, in a daring move ahead of her 29th birthday on Saturday, Jan. 12, Jana joined Instagram.
She's been known as the "Cinderella" Duggar because although she's the oldest sister, Jana hasn't started courting as all her sisters did young.
Counting On fans rejoiced about Jana jumping on social media at last, thinking it meant she'd found love.
Josh's wife, Anna, was the first to congratulate Jana for joining Instagram.
"Welcome to Instagram @janamduggar" Anna excitedly wrote.
Jana's first post was a photo of her two nephews, Jessa's sons, Spurgeon and Henry.
"Best buddies!" she captioned the shot.
Just last year, father Jim Bob humiliated Jana on her birthday by joking to a crowd that he is "still praying" she finds love.
The reality star was formerly linked to family friend Caleb Williams but he denied the reports he was dating Jana.
As RadarOnline.com exclusively reported, Caleb's older brother Joshua has been arrested for assault and battery against a child.
On December 3, 2018, he pleaded not guilty to the crimes.
At 29 today, Jana Duggar has long puzzled fans of her family's TLC show Counting On by remaining single. While her other marriageable age sisters have walked down the aisle and are having kids, Jana remains the holdout.
Jana revealed in one Counting On episode that some day, her prince will come!
"There have been different guys who have come along and asked, but they haven't been, I don't know, the right one," she claimed.
