As we noted earlier this week, the feud between Jenelle Evans and Kailyn Lowry is officially back on.
Granted, it was never really off, but the Teen Mom 2 castmates had been steering clear of one another for the past several months.
That changed this week when a new episode of the show dredged up some old hostilities.
Now, Jenelle is throwing everything she's got at Kail on Twitter, and we're reminded of just how ugly things can get between these two.
Take a look:
By now, you probably know the story -- Kail and Jenelle were close friends in the early days of Teen Mom 2.
Those Days Are Done
The friendship came to an abrupt end, however, when Kail and Jenelle clashed on social media and Evans went nuclear, as she tends to do.
There's some disagreement over what the final straw was, but it likely didn't help that Jenelle told the world Kail was pregnant with her third child long before Lowry was ready to make that announcement.
Back At It
Whatever the case, Jenelle and Kail are no longer besties -- but they mostly manage to stay out of each other's hair. Or at least they did until this week.
Back in December of 2018, Kail sent Jenelle some samples of her Pothead hair care line. For reasons that still aren't entirely clear, Evans lit those samples on fire.
Passing On the Peace Pipe
Jenelle was so proud of her decision to torch Kail's "peace gathering" that she posted a video of the incident on social media.
