Britney Spears' younger sister Jamie Lynn will reportedly head down the aisle before the year is out.

Despite rumours that all is not well between the new mother and fiance and baby-daddy, Casey Aldridge, a new report claims they are set to exchange vows in a low-key ceremony at their  home in Liberty, Missouri.

"She loves everything about the area where she lives,” a source tells OK!.

“She's not going to get married at some luxury resort in the Caribbean or a hotel in Beverly Hills.

"Her own backyard with just the people who matter most is more Jamie Lynn's style."

Jamie Lynn reportedly wants big sister Britney as her maid of honor, and Casey's sister Ashlee will be one of her bridesmaids.

The couple's one-month-old daughter Maddie may also make an appearance at the ceremony, carried in a basket by the bride and groom's mothers.

It was also claimed recently that Jamie Lynn is already planning her next child.

"Jamie Lynn is so taken with her little girl she wants to give her a sibling, preferably a sister, as soon as possible," revealed a source.
