Watch: Britney’s little sister filmed grabbing large knife in public brawl

Britney Spears' younger sister Jamie Lynn got caught up in a public fight recently, and now it seems the whole thing has ended up on camera.

The 23-year-old was lunching in the Pita Pit sandwich bar in Los Angeles when her female pal ended up in the middle of a large brawl between a number of men. It's not known whether Jamie and her friend knew the men, but it looks like things escalated pretty quickly.

Jamie was quick to act by pulling her friend away from the action, but things then took a dramatic turn when she moved behind the counter and grabbed a large knife.

The incident happened last month, but gossip site TMZ have today obtained this exclusive footage of Jamie waving the knife wildly in an attempt to break up the fight, while one of the café's workers tries to stop her:

Although it was definitely not the safest way to keep the peace, Jamie did succeed in calming the brawling men down.

We wouldn't want to get on the wrong side of the Spears sisters, that's for sure!
