Believe it or not, exactly zero Teen Mom cast members are more popular on social media than Chelsea Houska.
In fact, with 5.7 million followers on Instagram, Chelsea has the largest online fanbase by a wide margin.
The Housk's other account, documenting her home building journey, with her family has another 350,000.
That's six million in total.
For reference, her Teen Mom 2 co-stars Kailyn Lowry and Leah Messer have 3.8 and 2.3 million followers, respectively. Not shabby totals by any means, but nowhere near Chelsea's.
Houska's level of popularity may come as a shock to many fans - not because Chelsea is less well-liked than her co-stars, but because she lives a quieter, more drama-free existence.
Usually, a life of domestic contentment and bliss doesn't lead to reality TV stardom, but she's not your typical reality star, even if she rose to fame on one of the more popular franchises.
Chelsea is that rare example of someone who attracts viewers not because her problems make them feel better about their own, but because her life gives them something to aspire to.
We reported that Chelsea lost followers by the thousands last month when she neglected to comment on the police murder of George Floyd and the Black Lives Matter protests that followed.
But it was a rare slip-up for Houska, and fans were forgiving when she apologized and attempted to rectify the situation.
Her numbers quickly started inching back upward, which is good for her family, because Chelsea makes a ton of money from Instagram - more than $60,000 a year by one estimate.
And that's why - we swear we have a point - it's so surprising that Houska has essentially disappeared in recent weeks.
Don't get us wrong, she still pops up occasionally, but in the past six weeks - an eternity on the 'Gram, she's only posted twice.
Pretty infrequent, especially when you consider that Jenelle has probably posted twice in the time you've been reading this story.
We kid, but in all honesty, what gives?
The 28-year-old Chelsea earns more from sharing content on the social network than most people get paid in a year.
There must be a reason, no?
It's worth noting that those two posts consisted of a photo of her son Watson, and a closeup shot that only shows Chelsea from the neck up.
Interestingly, the decline in activity occurred right around the time that fans began to theorize that Chelsea is hiding a baby bump.
At first, the rumors seemed absurd.
After all, why would someone as universally beloved as Chelsea keep the joyous news of her pregnancy from the public?
Convinced that something is afoot in South Dakota, some observers think they know why she might be holding off on making an announcement.
The most common theory is that Chelsea is simply waiting until her second trimester, which is a common practice.
In fact, it's unusual for famous women to go public with the news of a pregnancy until they reach their third or fourth month.
Another theory is that Chelsea is hoping to earn more cash from sponsored content deals before she puts her modeling career on hold for a few months by necessity, though that seems unlikely.
After all, she and husband Cole DeBoer have both been earning six-figure salaries from MTV for several years now.
We think they can manage without her Instagram cash for a few months - that is, if it even declines. She might even be lining up deals to pitch maternity-related attire instead. Who knows!
Whatever the case, as far as we can tell, this is the longest that Chelsea has gone without posting a full-body shot, which is especially strange since we're in the middle of summer.
In years past, both Chelsea and Cole De Boer have delighted in showing off their toned abs in swimwear this time of year.
Or any time of year. These two hotties are cut.
Obviously, she could have a number of reasons for staying more covered up than usual. But it does make you wonder.
So if Chelsea is pregnant, we offer our heartiest congratulations, and can't wait for the official announcement when she's ready.
And if she just doesn't feel like reading troll-ish comments from people for awhile, well, we can definitely relate to that too.
