After attending, beauty blogger Jackie Aina (who most recently got into a controversial argument with Jeffree Star), posted a review of Kim's line on her YouTube channel.
Her verdict wasn't necessarily bad, it just wasn't glowing.
After it, Kim untagged Jackie from her Instagram post, and Twitter went at it.
Kim noticed the rage online, and sent out a series of tweets clearing the air.
"I just saw a story saying I intentionally didn't tag @jackieaina in a pic I posted on Instagram because of a review she did about my line. I would never post someone's pic on my page and then intentionally not tag them.
"When I uploaded the album I was tagging everyone that came to the party and for some reason it wouldn't let me tag Jackie's name. I figured I would just try again later, but then I realized you can't add tags after the album is posted! I hung out with @jackieaina in my home and she was super sweet!!
"I love that she has an opinion and I'll take what she said and use it to better my products.Honestly, I'm so thankful to everyone who is giving me feedback on my beauty products & I love hearing what everyone loves, and doesn't love. So @Instagram, can you change it so that you can tag people in galleries after they are posted, so I can avoid this issue in the future?"
Jackie also responded to Kim:
"When @KimKardashian invited us into her home for the launch of KKW she was very sweet and professional, I shared that with all of you. So when this happened I was confused. It wasn't about being recognized, it felt like I was being shaded for a less than perfect review ....and I know that's not just how it looked to me, it's how it looked to everyone else.
"I didn't notice the photo tag until you all told me.I don't know @KimKardashian personally, so while she was super sweet tbh it's hard NOT to assume the worst of people in this industry, but anywho thank you @KimKardashian for clearing that up, having me into your home and welcoming my honesty and feedback."
Just another dramatic day in the beauty industry.
