Jamie Lynn Spears, the sister of singer, Britney Spears, caught on video acting like a total bad ass after trying to break up a fight by grabbing a huge kitchen knife.

In video footage, we see Spears going behind the counter at a sub shop, picking up a knife and displaying it to the folks causing the ruckus.

The video, which has no audio, shows Spears in all of her true hickdom, taking charge by charging the offenders with a large knife.
