Jamie Lynn Spears hangs out with Casey Aldridge in Kentwood

Britney Spears' 16-year-old sister made a rare appearance in her hometown of Kentwood, Louisiana.

Carefully hiding her bump in a baggy hooded-sweatshirt, the pregnant 'Zoey 101' star took her black and white puppy to the vets Friday.

Jamie Lynn - who recently partied with pals while mom Lynn was away looking after her troubled sister - was reportedly wearing a similar over-sized sweatshirt to the one she was last photographed in leaving a GED class last month.

On Saturday and Sunday, Jamie Lynn went out with her boyfriend and father of her baby, Casey Aldridge.

Hand-in-hand, they went to a convenience store Saturday. Spears sported a white Heineken beer T-shirt that showed the faintest hint of her growing stomach, reports Us Weekly magazine.

The next day, Spears and Aldridge ran errands, stopping for a kiss every now and then.

Her dad, Jamie, is currently in Beverly Hills looking after Britney.
