Teyana Taylor and Rihanna got in a cray-cray war on Twitter, and there was some serious shade thrown.

Rihanna and friend (now ex-friend, we're presuming) Teyana Taylor engaged in an epic Twitter battle.

Two weeks ago, G.O.O.D. Music songstress Teyana Taylor posted an Instagram video featuring her a cappella rendition of Anita Baker's 'Caught Up In The Rapture.' All well and good, right?

But then yesterday, Rihanna posted an Instagram vid that showed her stylist-who was male-wearing a backwards hat and curly wig singing the song in an apparent parody.

That means war.

Taylor lashed out at RiRi, saying,

Don't play with me @Rihanna f-ck all this industry sh-t, YOU & I know each other very well. Throwing sub 4 wat? u got my #, don't show off."

Ruh-roh.

The Tweet's been taken down, but that was just the start of it, Teyana also said,

 "Y'all could bully everybody else & get away wit that sh-t but that sh-t ain't gone work ova here. So y'all could miss me with that NAVY sh-t," Taylor posted. Then finished her rant by saying, "Petty is petty and shade is shade, b-tch knew what the f-ck she was doing."

Rihanna threw some shade right back. Using more hashtags, obvs.

"I REFUSE to help your career...you will NOT get an @ from me! Not til you pay me! #nomorefreepromo #iRefuse"

Screaming in an empty room! #dontfeedtheanimals

Aaaaand it went on from there.

Check out the insanity below. Rihanna and Taylor lob beef back and forth like they're making burgers. In the shade. Which they're also throwing, along with the beef. Yeah, something like that.
