Last month Jamie Lynn Spears was making a late night stop at Pita Pit in Hammond, LA when a fight broke out. The fight was big enough that Spears' friend got caught up in it.

That's when Britney's little sister took matters into her own hands, quite literally. Spears marched behind that Pita Pit counter, picked up the 7-inch knife, and started brandishing it to the guys involved in the brawl. I don't know if it was her mother bear instincts kicking in, or maybe some hanger induced rage that this fight was preventing her from enjoying her pita, but whatever it was...it was enough to get the fight to break up. Check out the crazy video for yourself!
