Sources say that Mother of the Year Lynn Spears is pushing Jamie Lynn to get a prenup so that Casey Aldridge doesn't walk away with everything she has. Just in case he's a cheater. She thinks Casey isn't as committed to the relationship as Jamie Lynn, so she wants to make sure everything is in order before they walk down the aisle.
With the luck of this family so far, a prenum is actually a very smart move. I don't think this marriage would last long either heh.
