Jamie Lynn Spears’ new baby Maddie Briann has been born with a full head of hair and her “her daddy’s toes”.

The latest addition to the Spears’ family was born on Thursday in McComb, Mississippi and sources say the baby girl is doing great.

An insider tells People.com, “They're doing terrific. The baby's got 10 fingers and 10 toes and a full head of hair. She's long, a tall baby, and she weighs 7 lbs, 11 oz."

Father Casey Aldridge’s grandmother joined relatives including Britney Spears at the birth, and Joyce immediately spotted Maddie has inherited one of her family’s traits, remarking she “has Casey’s toes”.
