Jamie Lynn Spears is planning to wed fiancé Casey Aldridge in her hometown of Kentwood, Louisiana, it’s claimed.

The pregnant teen – who was spotted on Monday flashing her new engagement ring - is expected to stay true to her small-town roots by tying the knot at big sis Britney's "Serenity" estate.

"She'll have the baby there, and soon after, she will also get married there," a pal tells OK!.

"I expect she'll want to wait at least several months to get her figure back so she can wear a beautiful wedding gown and then have her dream wedding."

The Zoey 101 starlet - who turns 17 on April 4 - is also busy preparing for the birth of her first baby in late June.

She recently registered for her baby shower at a Babies 'R' Us store in the nearby city of Baton Rouge.
