At a post birthday bash gone berserk, pregnant teen star Jamie Lynn Spears was injured trying to break up a brawl while daddy-to-be Casey Aldridge was knocking back brewskis with his buds!

An estimated 500 teens showed up at a barn party April 5 at the home of Casey’s pal.

Despite security guards for crowd control, the police were summoned to investigate a possible sexual assault on a girl.

Jamie Lynn, who had just turned 17 the day before had been reluctant to attend but had agreed to be 18 year old Casey’s designated ditz – uh – driver.

Just past midnight two of Casey’s pals let their testosterone get the beast of them while jockeying for the same girl. Words and then fists flew – furiously! “Jamie Lynn decided she could break it up but got elbowed in the mouth by one of the boys,” said an insider.  “She went crazy, screaming at everyone!”

Security promptly ended the Spears-down but a distraught Jamie Lynn had a few choice words for her boozy fiancée. “Jamie Lynn kept asking Casey, ‘What if I would’ve gone into labor, what help would you be?’” the insider revealed. source
