Derick Dillard has made tabloid headlines several times in recent months, which isn't uncommon for members of his famous family.
Unlike his in-laws, however, the husband of Jill Duggar generally attracts more attention for his political views than his personal life.
That may soon change, however, thanks to rumblings that Derick Dillard may have cheated on his wife of three years.
Interestingly, Derick prompted the speculation himself with a series of biblical tweets that some have fans have taken as a veiled confession:
“He who commits adultery lacks sense; he who does it destroys himself," Derick tweeted earlier this week, adding:
“Say 2 wisdom ‘U r my sister’& call insight your intimate friend, 2 keep u from the forbidden woman, from the adulteress w her smooth words."
As OK! magazine points out, several fans jumped to the conclusion that Derick was talking about himself and coming clean about being unfaithful to Jill.
"Hmm.... sounds like SOMEONE might have a GUILTY CONSCIENCE," one fan responded.
"Sounds like someone doth protest too much," echoed another follower.
Several comments referenced the fact that Derick has been spending a good deal of his time on college campuses in recent weeks:
"Those college girls teasing you?" read one such tweet.
There's obviously no evidence of Derick behaving inappropriately with any of the young women who are participating in his campus ministry program.
Still, one fan on Instagram pointed out that Dillard appears to have deleted a recent post after being alerted to its sexually explicit nature:
"So, what happened to the post about the dance and the music? Why did Derick delete that entire post?"
"Was it because people pointed out that the music (sung in Spanish) was very sexual in nature?" the follower added.
"And for someone who can supposedly speak Spanish (lol), how did he not know that before posting it?"
"Could his claims of knowing Spanish be just another lie? So many lies, too little time."
Other fans interpreted Derick's remarks differently.
For instance, it could be further condemnation of his brother-in-law, Josh Duggar, who famously got caught cheating on wife Anna Duggar in 2015.
"You are promoting rumors and gossip about yourself when you do this. If you have issues with your brother in law, just say it," another fan tweeted at Derick.
As stated earlier, this is far from the first time that Derick has drawn the ire of fans on social media.
Back in August, Derick launched a Twitter attack on Jazz Jennings, a transgender teen who, like Dillard, stars in a TLC reality series.
"What an oxymoron... a 'reality' show which follows a non-reality. 'Transgender' is a myth. Gender is not fluid; it's ordained by God," Dillard tweeted at the time.
Earlier this week, Derick tweeted about racism in America in a way that left many fans with the feeling that the 28-year-old is insensitive to the plight of minorities.
"The US is one of the least racist countries in the world. In unity, let’s strive to protect & improve this anomaly in history," Dilard wrote.
Not surprisingly, the post wasn't terribly well-received.
Thus far, Derick has yet to respond to this latest controversy.
Of course, Dillard's never been one to shy away from conflict, so we're guessing it won't be long before he claps back.
In all likelihood, Derick will be running his mouth on social media again before the week is out.
And it's anyone's guess as to how his father-in-law will feel about that.
Sources say Jim Bob Duggar has been clashing with his sons-in-law over two main issues - differences in religious doctrine, and the future of the family media empire.
Jim Bob and Derick are said to be largely in agreement on the former issue.
But we're guessing JB is less than thrilled with the way Dillard's been rolling the dice with his in-law's reputation lately.
