Jamie Lynn Spears gave birth to a baby girl yesterday morning at a south Mississippi hospital, according to a person close to the Spears family.

The person confirmed the baby’s birth to The Associated Press. The person asked not to be identified because the family had not yet announced the baby’s birth.

The baby girl has been named Maddie Briann, according to a People.com report.

The 17-year-old was the star of Nickelodeon’s Zoey 101, a sitcom about prep school friends, and is the younger sister of pop star Britney Spears. The Spears family announced in December that Jamie Lynn was pregnant. The father is Casey Aldridge, a pipe-layer from Liberty, Miss. The couple announced an engagement several months ago.

Spears announced her pregnancy through an article in OK Magazine and was expected to receive a large payday for exclusive pictures of the newborn.
