Jamie Lynn Spears' Labor Day Love

Jamie Lynn Spears grabs lunch at a restaurant with a gal pal and newborn daughter Maddie Briann, 10 weeks, in McComb, Mississippi late last week.

The 17-year-old new mom wore a pretty-in-pink “Chillin’ in the Club” t-shirt and short green athletic shorts. Noticeably missing was her teenager fiance Casey Aldridge.

Jamie Lynn carried around baby Maddie in the carseat portion of her Graco MetroLite Travel System in Cherry Blossom.

FYI: Jamie is using her Graco infant seat!
