Jenelle was sitting at her dresser with her brown her styled into wavy curls and she lip-synched some dialogue originally said by Cardi B.
She was pretending to apply foundation as she mouthed the dialogue.
"I know for a fact that y'all think I'm r****ded, and the crazy s**t is that I am, I am. I really am," she lip synched before looking to the camera with a wry smile.
Many of her fans rushed to tell the former reality star the word was offensive.
One of her followers wrote: "Ooo no. Let's not use that word."
Another said: "You don't use that word. The fact you do shows exactly the kind of person you are."
A third added that the "R-word makes my stomach turn".

"Sorry if I offended anyone!" Jenelle said in a reply to one of her followers.
