Kim told her sibling she had Botox jabs “two nights ago” before telling Kourtney: “Good for you”.
Elsewhere in the episode, Kim opened up about her experience of studying for the bar exam as part of her mission to become a lawyer.
Kim revealed she was suffering back problems before the test, saying: “’I threw my back out and it’s like … every time I think I get to another step, something pulls me back,.
“There’s all these f****** roadblocks. I’m not, like, a pity party kind of girl, but, like, last night, I was like: ‘Why the f*** is this happening?’
“I can hardly walk. I can hardly f****** sit. I don’t know why I have all these back problems.”
Kim revealed in November she had failed the exam and will now have to retake it if she wants to qualify as a lawyer.
She recently told Time magazine: “I took a minute to process that, and instantly, when I got my results, I didn’t feel good about it.
“I was really uncomfortable and not confident for a while. You get the results on a Friday, and I knew Sunday morning they were going to be live on the internet.
“So I wanted to mention it first and let people know that it didn’t go my way. So, instantly I was like, okay, let’s do this, I know what I’ve got to do.”
Kim said she felt low about failing, but she’s determined to get back to work and pass the exam next time.
“This really sucks because I put so much time into it, but I know what I can do better.
“I’m pretty good at taking a failure and turning it into something and I just don’t have the time to dwell. You can feel sorry for yourself for a second, but I need to take that time and put it into studying more.”
