Jessica Miller is the sister of Jenelle Evans' husband, David Eason.
She's never appeared on Teen Mom 2, and it seems she has little face-to-face contact with Jenelle.
Still, in the world of TM2 obsessives, Jessica is something of an icon, thanks to her stunning ability to match Ms. Evans in terms of violent insanity.
Jenelle and Jessica's feuds are the stuff of legend, often spilling from one social media platform to another, as each attempts to publicly throw shade without the other one knowing.
It's a thrilling game of cat and mouse, in which both the cat and the mouse accuse one another of being meth addicts.
Jessica accuses Jenelle of doing drugs while pregnant.
Jenelle accuses Jessica of driving while high and getting fired for stealing prescription painkillers from work.
And we all look on in amazement and thank the heavens that our families are downright functional by comparison.
Unfortunately, it looks like the schadenfreude might be coming to an end, as Jessica will likely be doing her best to keep her nose clean for the foreseeable future.
According to Starcasm, Jessica was arrested for assault over the weekend
There's no word on who Jessica may have assaulted, but it's worth noting that she got into yet another Facebook fight with Jenelle the day before the arrest.
This time, Jenelle unequivocally initiated the spat, by posting this deranged "review" of Jessica's t-shirt company:
"Fake business!!!!! This owner is psycho! She threatens people on a daily basis on social media saying she’s going to fight them and such.
"She also doesn’t own one piece of this clothing at all and uses an “art” app on her phone to copy and paste texts onto shirts without even testing them out herself.
"She tried stealing a logo from another company. I ordered a shirt a week ago and it’s still not here. I asked to be refunded and it’s taking forever! Really upset with this company! Never shopping here again. Maybe if the owner wasn’t on drugs this business would be ran properly."
We don't know what's funnier--the fact that Jenelle has gone full-Trump and is now calling everything she doesn't like "fake," or the fact that tried to legitimize the whole thing by slipping an actual complaint about delivery time into unhinged psycho-screed.
Interestingly, an Instagram follower recently asked Jessica why she's never gotten into a physical altercation with Jenelle.
David's sister had this to say in response:
"I came really close to it when i had to go to court with her and barbara over jace. I followed her into the bathroom and i told her what an ungrateful selfish little B she is but i kept my hands to myself bc she isnt worth jail time or my money in court costs! "
Perhaps tellingly, Jenelle hasn't taken to Twitter to boast about Jessica's arrest, as one might expect her to.
We're not saying Jessica and Jenelle got into a fight, but we certainly wouldn't be floored by that news.
We'll keep you updated on the situation as more information becomes available.
In the meantime, watch Teen Mom 2 online to remind yourself of just what a brawler Jenelle is.
She's not someone you wanna mess with...
