Kylie and Stassie have been friends for a long time, and in a video interview for Teen Vogue, Kylie gushed over her friend, saying: "You've been the most consistent and loyal friend in my life.

In other news, Kylie's representatives have put to rest rumours that she and boyfriend Travis Scott got married earlier this week. A source told HollywoodLife that if Kylie were to get married it wouldn't be a secret affair.

"Trust me, when Kylie does get married, it most certainly won't be in secret—do you really think Kris Jenner would allow that to happen?" the source said. "Not when there's that amount of potential money and publicity at stake!"
