Jamie-Lynn on the final stages of her pregnancy, the 17-year-old has been readying the new Mississippi home she shares with fiancé Casey Aldridge for the birth of their first child.

"They're very happy," says a pal of the couple.

"They're just a sweet little old couple," adds a neighbour.

The couple chose the furniture - including a four-poster king-size canopy bed and a leather sofa - for their new home themselves, mum-to-be Jamie has enlisted the help of her own mum Lynne to lend a hand decorating the nursery in pink, brown and silver-green hues.
