Kim Kardashian reveals what the mysterious "cocaine lines" really are...

Kim Kardashian has slammed allegations that she uses cocaine.

Eagle-eyed fans noticed what appeared to be two lines of a white powdery substance in the background of one of her social media clips on Monday.

One Twitter user wrote: 'Ohhhhhh @KimKardashian caught out with cocaine .. durtayyyyy.'

The Keeping Up With The Kardashian's star tried to put out the fire on Tuesday morning, writing on Twitter: 'I do not play with rumors like this so I'm gonna shut it down real quick. That's sugar from our candy mess from dylan's candy shop.'

But fans didn't buy her excuse, with one person replying: 'You keep your sugar in cut lines? neat'.

Another replied simply: 'yea candy'.

The 36-year-old later realised it wasn't actually sugar on the table after all. Yep, that's right, all along it was just some marbling on a table top.

Kim has talked about her stance on drugs previously, telling Jay Leno on The Tonight Show in 2010: 'I've never been a drinker, I've never gotten into drugs.

'You know, I think I have such a close family. I think, you know, at a young age. I think you know my sisters do enough drinking to kind of fill up the whole family....From a young age, my dad made it very clear that, "OK, you're the responsible one and you have to watch your sister, and (he) taught me how to drive when I was 14 in case my sister or her friends were going to be drinking and I always had permission to drive.

'You know, I had to call him from the destination and the final place. I always felt this sense of pride that he had in me that I was the responsible one so I always wanted to make him proud. And I hate the taste of alcohol.'
