Kylie Jenner turned 18 years old in August, enabling us to finally publish some photos of the reality star without feeling like dirty gross old men.
But while Kylie"s milestone of a birthday was good news for millions of males around the world who could not ogle her Instagram account guilt-free, it was initially bad news for sisters Khloe Kardashian and Kourtney Kardashian.
How come?
Because she failed to invite them to her birthday party!
At least at first, as we discover in the following clip from Keeping Up with the Kardashians.
It features Khloe and Kourtney talking about Kylie"s planed shindig and wondering why the heck they had not received an invitation.
So Khloe calls up Kylie to get to the bottom of this snub, pretending that she has an event on the scheduled party date and giving her younger half-sibling a hard time.
In the end, of course, Kylie did host a birthday rager in Montreal, making A LOT of money from it in the process.
Khloe and Kourtney were on hand to celebrate the occasion with other family members, easing concerns of anyone who believed there was real family tension here.
But check out the following clip to see how the siblings reacted upon thinking they were being dissed by Kylie and then to see how Khloe turned the tables a bit on her loved one.
You can then watch Keeping Up with the Kardashians online after this episode airs to see what else transpires.
