Jamie Lynn Spears’s mother has demanded her daughter gets a pre-nuptial agreement before marrying Casey Aldridge.

According to In Touch magazine, Lynne Spears is worried the 17-year-old will lose all her earnings from TV show Zoey 101 if the relationship falls apart.

A source said: “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.”

It was reported last month that Jamie Lynn and Aldridge were engaged. The pair are expecting their first child in the summer.
