Saturday night in Brooklyn Salt -N- Pepa performed at the '90s Fest and "Pepa" spilled all over the floor.

So this is what happened. Salt-N-Pepa were performing "Sweet Child O' Mine" when Pepa tried to jump from one speaker to another and slipped.

Word is that there was some water on the speaker and that's what caused her to slip. She got on up and only ended up with a couple of bruises on her legs. But ouch! That had to hurt bad!
