Kim Kardashian has reached a major milestone: On Thursday, the reality star hit 27 million Instagram followers.

The momentous occasion came just a few days after younger sister Kendall Jenner also hit a large number on Instagram—20 million followers—and both sisters celebrated by posting selfies as thanks to their fans.

Kardashian captioned her slightly racy shot with, "27 mil on Instagram!!!!! Thank you so much!!!! I love you all!!!!!"

Jenner posted her selfie on Wednesday and captioned it: "Ask and you shall receive. selfie for all 20 mill of you. thanks for all the love.” Great minds think alike.

It's been a big week for the Kardashians. Earlier in the week Kris Jenner signed a $100 million contract with E! for four more seasons of Keeping Up with the Kardashians, People confirmed. Kris, Kim, Kendall as well as Khloé Kardashian, Kourtney Kardashian, and Kylie Jenner have all signed on for the upcoming seasons, which includes possible spinoffs and a YouTube channel. It may also lead to more hosting gigs for the women with the network (Khloé regularly covers awards shows) and producing new projects—in other words, it's only a short matter of time before Kim and Kendall are celebrating even bigger Instagram follower milestones with more selfies!
