Sister shade? Jill Duggar celebrated her birthday on Thursday, May 17 — but Jinger didn't share a tribute on her special day. Instead, the Counting On star posted a throwback photo with her "bestie" Jessa. #Awk. Watch the video above to see the pic!

Yet this isn't the first time the pregnant 24-year-old was passive aggressive towards Jill. Last month, Jinge took to Instagram to snap a photo of herself holding a not-so-subtle book. "Hey single ladies, you may be interested in reading a book I am going through with some of the other women from my church— She's Got the Wrong Guy: Why Smart Women Settle by @deepakreju. Jeremy and I read it together and really enjoyed it || Search for it on Amazon! ||"

The message came just two days after her brother-in-law, Derick Dillard, posted his unwarranted comments on Nate & Jeremiah by Design stars Nate Berkus and his husband, Jeremiah Brent. "What a travesty of family," he wrote on a promo for the home improvement show. "It's sad how blatant the liberal agenda is, such that it both highlights and celebrates a lifestyle so degrading to children on public television as if it should be normal."

Recently, the reality TV exile — who was fired for his transphobic remarks on Jazz Jennings — has been losing followers, including Ben Seewald. Redditors recently pointed out that Jessa's handsome hubby clicked the unfollow button on social media, as did a member of the Bates family.

"The shunning begins… the Bates family have unfollowed Jill and Derick. Individual accounts unfollowing just Derick, meanwhile Ben unfollowed him, who's next?" To which someone replied, "I predict that someone at Cross Church is going to have a 'counseling session' with Derick and then his account will abruptly disappear. For as much as they probably agree with what he's saying, at some point, they don't want to be responsible for negative attention that this will invariably draw." Another agreed, "What he is doing is incredibly tacky. Twitter is not the place for personal, family or business grievances."

So will Jinge follow in Ben's footsteps? It certainly looks that way. Then again, with 19 siblings, maybe she simply forgot it was Jill's birthday.
