LOS ANGELES, July 27 (UPI) -- Khloe Kardashian has denied rumors of cocaine use at half-sisters Kendall Jenner and Kylie Jenner's high school graduation party.
The 31-year-old reality star slammed such reports after Kylie Jenner posted a clip of Kardashian twerking on Snapchat. A friend can be seen dipping his finger into a small container and putting the finger in his mouth in the background.
