Watch Jamie Lynn Spears Break Up a Fight With a Knife - VIDEO

Once upon a time (last month to be specific), a lady friend of Jamie Lynn Spears got caught in the middle of a brawl in a Pita Pit in Louisiana between several not-so gentlemen.

During the melee, Jamie Lynn went all mama bear and broke the skirmish up by brandishing a knife.

We would like to thank TMZ for getting hold of the security footage, which features Spears taking control of the situation. By heading behind the sandwich counter and grabbing a 7-inch knife.

Granted, it's a serrated bread knife, but it still seemed to get the job done as the men quickly disperse after getting some harsh words from Brit Brit's little sister.
