It looks like Michelle and Jim Bob Duggar’s second oldest son, John David, might be the next to walk down the aisle. The “19 Kids and Counting” reality-TV star has recently been spotted with a mystery woman, OK! magazine is reporting.

According to the tabloid, John David, 24, the twin brother of Jana Duggar, has been photographed out-and-about on several occasions with an unidentified brunette female. While the TLC reality-TV family has yet to confirm if John David is their next offspring to court, some evidence of his rumored romance has been uncovered on Instagram.

The Inquisitr reports that Instagram user Masiespace, a speculated close friend of the Duggar family, has captured several photos of the second eldest Duggar sibling and his speculated new girlfriend. One of the photos showed the brown-haired woman smiling and dining with John David. She was also reportedly photographed at a recent Duggar Family Resource bookstore event.

While the mystery woman appears to be close to John David, some are also speculating that another brunette, Masiepsace herself, could also be his new leading lady. Not only has Masiepsace, a Christian who goes by Laura D. on Twitter, posted selfies with all of the Duggar girls on her account, she was also the only non-family member to pose for a photo with the Duggar clan in front of their famous RV eight months ago, The Inquisitr reports.

John David, the owner and operator of Duggar Towing, opened up about his personal life with People magazine earlier this month. “I am such an expert in love and marriage,” he joked, later adding, “Everybody is giving me advice about getting marred. It isn’t a big thing. I’m open to advice.”

If John David is courting, he will be the fourth Duggar kid to do so. Michelle and Jim Bob’s oldest, Josh, 26, has three kids with his wife Anna and a speculated fourth on the way. The couple’s second eldest daughter, Jill, 23, married Derick Dillard, 25, in June. The couple is expecting their first child together, a boy, this spring. Jessa Duggar, 22, married her now husband Ben Seewald, 19, earlier this month. The couple is currently celebrating their honeymoon in Paris, France.

“19 Kids and Counting” airs Tuesdays at 9 p.m. EST on TLC.
