Don’t mess with Jamie Lynn Spears! The not-that-innocent younger sister of Britney Spears broke up a fight at a sandwich shop in Hammond, Louisiana in December by pulling out a knife and brandishing it at the group brawling.

On Tuesday, Jan. 13, TMZ released the security cam footage of the incident, which features the Nickelodeon alum, 23, going behind the counter of the Pita Pit and grabbing a large serrated knife. Moments later the fight breaks up as customers put their hands up to avoid the country singer and her blade. 

Back in December, cops told TMZ that Spears’ friend was knocked over during the fight, which involved a group of guys. 

The mother of 6-year-old Maddie has not publicly spoken about the incident. Find out more about the bizarre moment caught on tape.
