A heavily pregnant Jamie Lynn Spears was elbowed in the kisser after attending a drunken teen party with fiance Casey Aldridge on April 5th. More than 500 teens attended the bash, where Casey was spied downing cans of draft and an unidentified girl was sexually assaulted.

According to a new report from The National Enquirer, Jamie Lynn was injured when she attempted to break up a fight between two of Casey’s friends:

“Jamie Lynn decided she could break it up, but got elbowed hard in the mouth by one of the boy,” says an eyewitness. “She went crazy, screaming at everyone….crying, screaming, and covering her mouth.”

“Casey was so drunk, he just kept trying to hush her up.”

Lynne Spears was one person who wouldn’t hush up: “She called Jamie Lynn and bitched her out for going. Jamie Lynn’s dad Jamie called Casey and told him if anything happens to his daughter, he will have to deal with him.”
