No marriage for Jamie Lynn Spears and Casey Aldridge without prenup?

So knocked-up 16 year old Jamie Lynn Spears is now engaged to Casey Aldridge, 18, but there will be no shotgun wedding. In fact momma Lynne Spears isn’t so sure if marriage is such a good thing for her daughter and wants some protections put in place.
Lynne is rightfully said to be insisting that the couple sign a prenuptial agreement.

A source tells In Touch Weekly, “The contract is already drawn up and ready to go. Lynne’s not sure marriage is a good idea, but she’ll go along with that if that’s what Jamie Lynn wants, as long as Casey signs the contract.”

A family friend says Lynne is worried about Casey and is aware of rumors that he may have cheated on Jamie. The friend adds, “Lynne is keeping an eye on him. He doesn’t seem as committed to the relationship as Jamie Lynn.”

Momma Lynne is currently back in Kentwood to celebrate Jamie Lynn’s 17th birthday April 4th. They grow up so fast!
