Unfortunately, one of those 'deleted tweets' shows Rob making awful comments about his step-father, Caitlyn Jenner.
"My mom keeps telling me to stop, but she was married to a dude named Caitlyn, so I'm def not listening to her 😂," he wrote.
Rob crossed many lines yesterday, but this one is a step further by being awfully transphobic.
It is unknown whether or not the tweet is 100% real or just a photoshopped image made online, but regardless, it's disgusting.
Nothing that Rob did yesterday is okay, and he may be facing many legal charges because of it.
The Kardashian sisters have expressed their disappointment in their brother since the whole drama went down, as they are "are adamant ... ANY public feuding between Rob and Chyna is unacceptable."
"They are ashamed the war has become a public spectacle and hurting the family name. Even worse than damaging the brand, family members worry Rob and Chyna are hurting 7-month-old Dream," TMZ reported.
What a mess.
