Jamie Lynn Spears has found herself tangled in a web of prenup drama as she prepares for impending teenage motherhood. The seventeen year old is due to give birth to her first child with boyfriend Casey Aldridge next month, but she has refused to marry the nineteen year old construction worker until he agrees to sign a prenup designed to protect the Spears family fortune.

“Casey doesn’t want to sign the prenuptial agreement,” an insider tells In Touch Weekly. “It’s really causing a strain on everyone. It’s been going on for months and he still won’t sign it.”
