Baby Spears is a momma! Jamie Lynn had a C-Section this morning at approximately 8:30 am central at Southwest Regional Medical Center in McComb, MS., and is reportedly resting well. The baby girl has been named Maddie Briann, her middle name probably in honor of Jamie Lynn and Britney’s brother Brian. Maddie weighs 7 pounds, 11 ounces. Her father is Casey Aldridge. Welcome to the world, little one.
