Rapper Cassper Nyovest has performed at hundreds of shows across the country but we have a feeling that he will remember this past weekend's show at uShaka Marine World for a very long time.

That's because the rapper slipped while performing a song at the Nickelodeon slime festival on Saturday.

He had just taken to the stage to perform the hit Jump when he took an unexpected tumble.

He got up quickly and brushed it off as if nothing happened, but the crowd had seen the slip and cheered him on.
