This rumor really blows, according to Kim Kardashian.

According to TMZ, the model & TV personality took to Twitter to refute rumors that she's on cocaine, after an Instagram video with two white lines on a counter top raised some eyebrows. However, Kim isn't having it.

She insisted the substance that was seen in the video was sugar, explaining that it was "from our candy mess from Dylan's candy shop." The candy thing makes sense, since she was photographed with North West shopping for sweets on Sunday in New York City. As for the placement in the video, does anyone arrange sugar that straight? Who knows.
