LOS ANGELES (PIX11) – Pop singer Britney Spears’ younger sister Jamie Lynn was involved in a wild brawl at a Los Angeles restaurant last month, and newly-released surveillance video shows the moment she grabbed a massive knife and walked coolly back to the scrum  — allegedly to break up the fight.

Spears, 23, was partying with a friend in December when they decided to grab a bite at Pita Pit, a sandwich shop in Hammond, Los Angeles.

Once inside, surveillance video shows a group erupt into blows toward the front of the restaurant.

Then the Spears can be seen grabbing a long, serrated bread knife from the counter after her friend caught a bottle in the head.

Spears can be seen walking directly back to the group of combatants, knife in hand, as people separate and head for the door.

Her friend later declined to press charges; no arrests were made at the scene.
