Kendall confirmed the news herself on her social media and revealed that her username is @kendalljenner, (and not @kenjen as Kylie mistakenly stated when she excitedly first broke the news!)
With her little sister being one of the most followed people on the platform, Kendall and her fellow Snapchat newbie, big sister Kim, will have plenty of catching up to do.
So far however, both have been very active users of the app which isn’t surprising considering how addictive it is!
Kim often uses Snapchat to show off her sense of humour as well as share brief insights into her personal life. Both daughter North and hubby Kanye regularly appear in her Snapchat videos.
Even though Kendall has only been using the app for little over a day, she too looks set to be a very active user. So far, she has posted pictures from the Kendall + Kylie for Nordstrom event, as well as a number of selfies and videos.
We can’t wait to see if rumoured boyf Harry Styles makes an appearance!
