Kylie Jenner may be the reigning queen of Snapchat, but it seems she's got a little competition from her siblings. Kourtney Kardashian is officially on the social media site along with a few other members of her famous family.

Late Monday evening the mother of three posted an Instagram photo of herself sitting on sister Khloé Kardashian's lap while aboard a private airplane. The photo was adorned with several emojis, including an earth and an airplane. In the caption Kourtney shared her Snapchat username, giving fans the opportunity to find her and follow along on her current adventure and those to come.

Kourtney is hardly the only member of the Kardashian-Jenner family sharing peeks into her live via fun, short videos and photos. Kim Kardashian and Rob Kardashian are both also avid users of the app, created in September 2011. There have been rumors that Kendall Jenner also has an account, but that remains unproven. According to Us Weekly, Rob, 28, joined Snapchat on Feb. 2, showing off his bearded face and uttering a difficult to understand phrase. The Shade Room was able to grab that video, but did not release his username. Rob took it upon himself to share that information on Monday. Sister Kim, 35, hopped aboard the Snapchat train shortly after her little brother, joining on March 9. She posted her first official snap on March 15, which featured Kourtney, 36, and her signature.

Kylie has been an avid Snapchat user for some time now. She frequently uses the app to give viewers exclusive glimpses at things she's working on — like her Puma collection and her lip kits — and just goof around with friends. Kylie has also used Snapchat to keep rumors about her relationship with Tyga at bay, posting videos of them engaged in some serious PDA. Kylie can be found on Snapchat by searching this username: kylizzlemynizzl.
