It’s officially on between two of the biggest trainwrecks in Teen Mom history.

Despite having never appeared on the show together, Farrah Abraham and Leah Messer are now at each other’s throats after Farrah picked up on a subtle Twitter diss from Leah and (of course) turned it into a much bigger deal.

It all started when Farrah attacked a producer while filming the upcoming season of Teen Mom: OG. 

The ugly incident was featured in a newly-released trailer, and current and former cast members have all sided with Larry Musnik, the show’s beloved co-executive producer who was punched and kicked by Abraham.

The other Teen Moms have called for Farrah to be fired from the show, and while Leah didn’t go quite that far she did subtly diss Farrah and declare her loyalty to Musnik on Twitter:

“YAY! Can’t wait to watch my OG favs! @MaciBookoutMTV @CatelynnLowell @AMBERPORTW00D #TeamLarry #sorrynotsorry”

Farrah, of course, didn’t miss the fact that she wasn’t mentioned as one of Leah’s “OG favs” and she clearly took offense at the fact that Leah is proudly on Team Larry.

“I’m further along in life than she is and I just wish her all the best with her kid,” Farrah told OK! magazine in response. “I heard she lost her kid—maybe she should focus on that.”

Farrah is referring to the fact that Leah recently lost custody of her twin girls to ex-husband Corey Simms, and yeah, it’s pretty much the ultimate low-blow.

Not only is Leah dissing Farrah’s mothering skills, she couldn’t even be bothered to get the number of children right!

We get the feeling we haven’t seen the last of this feud.

Even if Leah decides to just drop it, surely some of her TM2 BFFs will get her back.
