Oops, Britney did it again, and this time with knives. Spears posted her famously viral dancing videos on Instagram, but this time she's dancing with knives, two butcher knives to be exact. The caption from Monday's video was, I started playing in the kitchen with knives today. There are reports out there stating Spears has a fascination with knives and keeps them all around the house to protect her. But this video is just scary and alarming to me. What do you guys think?
