Happy Monday! While you were (maybe) sleeping, Kim Kardashian unveiled a potentially damning series of videos of Taylor Swift possibly-maybe agreeing to Kanye West's "Famous" lyrics yesterday on her Snapchat (July 17), which just happened to be National Snake Day (the timing) — and Twitter went in last night.

But, in the middle of everyone's feverish tweets about the controversy, some famous friends (and foes?) decided to indirectly chime in with their mostly indirect support...or shade.

Selena Gomez, a known key member of Taylor's #squad, went in with a series of frustrated tweets assumed to be about the petty party.

"There are more important things to talk about... Why can't people use their voice for something that f--king matters? Truth is last thing we need right now is hate, in any form. This industry is so disappointing yet the most influential smh," she wrote.

Chloe Grace Moretz, who actually happened to subtly dismiss Taylor Swift's "squad" mentality not too long ago but traded barbs with Kim K. over a nude selfie earlier this year, also went in.

"Everyone in this industry needs to get their heads out of a hole and look around to realize what's ACTUALLY happening in the REAL world. Stop wasting your voice on something so petulant and unimportant," she wrote on Twitter.

Khloe Kardashian evidently saw those tweets real quick, and clapped back — perhaps a bit too hard — with some crude wordplay on Chloe's call for peace.

"Is this the a hole you're referring to @ChloeGMoretz ???," Khloe wrote to Chloe with a paparazzi photo of Chloe's exposed butt from the set of Neighbors 2 (if you're still following along, kudos to you), who wrote back with some clarification of her own — and, oddly, some additional promo for her new movie.

And while Demi Lovato didn't actually (body) say anything, she did like one very telling tweet during the fiasco last night: "I LOVE KIM KARDASHIAN 🍑😂👏🏻👍🏻." To be fair, this wouldn't be the first time she's thrown some shade Taylor Swift's way on social media.

And let's not forget Katy Perry! Although the Teenage Dream pop princess didn't really provide any direct "Bad Blood," either (or Hillary Clinton GIF reactions, sadly), she did promote her new song with a rather telling subtweet — her usual form of online fighting.

"#RISE above it all," she wrote in the middle of the Twitter spat. Enough said?

In conclusion: mess.
