It's Tokyo Toni vs. Caitlyn Jenner.

The mother of Blac Chyna -- Rob Kardashian's ex-fiancée -- unloaded on Rob's former stepparent in an expletive- and slur-filled minute-long transphobic video rant that was posted on World Star Hip Hop's Twitter account on July 15.


Listen at your own risk, as it's brutal.

"Hold up, hold up, did I just wake up to some m-----f-----' hot, stinky, pissy-smelling tea?" Toni (real name: Shalana Jones-Hunter) begins.

"Did that m-----f-----' n---- Caitlyn Jenner, aka Brucie -- yeah, big b----, little d---, him; look at them m-----f-----' Wheatie shorts -- this m-----f-----' n----, 'cause he's a man, dressing and pretending to be a woman using vocal chords like [talks in deep voice], b----, get it together, all that money you got, get a vocal coach!" she continues.

"How the f--- your stinkin' a--, n----, 'cause you got a d---, n----, you was born a man, n----, you gonna down your f-----' son and say he's stupid instead of saying something encouraging? And you gonna lie and say you don't know Blac Chyna?... Call me, b----, I got some words for your a--."

Toni also called Caitlyn, who transitioned into a women in 2015, an offensive gay slur: "f-----."

Toni's rant followed Caitlyn's recent appearance on "The View" in which the Olympic athlete and former reality star was asked to weigh in on Rob's vicious social media attack on Chyna in early July in which Rob accused his ex of cheating on him and having expensive plastic surgery to get her pre-baby body back and also posted explicit nude photos. (Chyna has since been granted a restraining order against Rob.)

"I don't know the Blac Chyna-Rob thing. Rob was stupid for doing that and he kind of apologized," Caitlyn said on "The View" on July 14, adding, "I really have not had much of a relation[ship]... I've never met Blac Chyna."

Caitlyn, who split from Rob's mother, Kris Jenner, in 2013, also admitted, "I've never met [their daughter, Dream]. Rob, I haven't really had a serious conversation with in years. So I've kind of been out of that scene so I really can't comment on what's going on there."
