She added that she feels the problem has to do with pressure online.

'If she just didn’t have access to social media or just stopped looking at the blogs, I think that she would start to feel better,' said the mother of three.

It's not clear why Kim is so rude to Khloe.

She then later asks Kourtney: 'And like, what the f*** is taking you so long? Like, I can’t handle being alone with her in the closet.'
