The 17-year-old sister of pop star Britney gave birth to Maddie Briann, her first child with fiance Casey Aldridge, at Mississippi Southwest Regional Medical Center in McComb, Mississippi on Thursday.
Family patriarch Jamie, who was said to be present at the birth, insists the entire family are delighted with the newest member of their clan.
He tells America's Life & Style magazine: "We're thrilled, we're all absolutely thrilled."
