The posts, which announced the launch is going down on June 21, garnered over 300,000 views and 1,000 comments altogether in under an hour — and fans seriously cannot contain their excitement!

“It was about time!” one fan wrote in the comments. “You paved the way for the makeup community and set mostly all the trends for us. Can't wait!!!” While others just wrote enthusiastically, “Take my money!!”

Though most people took the post as an opportunity to tag their friends and share in their excitement, others were a little put-off that the 36-year-old was inserting herself in her baby sister’s territory.

“[You’re] copying Kylie! Love [you] Kim, but leave that to Kylie,” one commenter wrote, while another added, “You couldn't stand the fact that your younger sister [Kylie] was succeeding in her Beauty business that you had to copy her and to top it all copy her colors? How rude and unprofessional you are!! So sad!!!”

This isn’t the first time there’s been some competition between the bootylicious sisters! Back in April when Ky announced her reality show, it was revealed that Kimmy wasn’t too fond of the idea, reportedly.

“Kim is really not feeling Kylie and her ability to make money hand over fist and she’s blaming Kris!” a source told Hollywood Life. “Kylie’s the golden child and Kris is giving her so much attention. It’s annoying Kim and making her jealous.”

Well, we guess imitation is the sincerest form of flattery!

Is it June 21 yet?!?
