We reported earlier this week that they bought a house.
Now Jamie Lynn Spears and Casey Aldridge are in full-on nesting mode.
The parents-to-be, who recently purchased their first home together in Liberty, Miss., are preparing for the imminent birth of their child.
"They're very happy," says a source. "They're a fun little couple."
To get settled, Jamie Lynn Spears, 17, and Casey Aldridge, 19, recently had furniture - including an elaborately carved four-poster king-size canopy bed, a leather recliner, and a leather sofa - delivered to the house.
As Jamie Lynn's baby bump grows and grows, her mom, Lynne Spears, is helping her decorate the nursery, with the color scheme of pink, brown, and "silver-green," according to an insider.
