Kim Kardashian took to Snapchat to unleash a foul-mouthed rant aimed squarely at her sisters Kourtney and Khloe after they “rudely” kept her waiting.

The girls had left their sister waiting for her personal trainer for half an hour – after they turned up late to their session with the same coach.

And Kim took to Snapchat to let them know just what she thought of them.

“So me and my friend Nikki are waiting for [our trainer] Joe to get here because my sisters’ workout ran 30 minutes late,” she said.
