Jamie Lynn had "perfect pregnancy"

Jamie Lynn Spears has given her first interview since the birth of daughter Maddie Briann last month.

The 17-year-old told OK! that she was nervous about delivering her first child.

She said: "It all fell into place. I was right on schedule. I had a perfect pregnancy and a perfect delivery. I was very blessed."

Spears also explained how she and fiancé Casey Aldridge decided on their daughter's name.

"Maddie is a name that Casey thought of, and I really liked it," she revealed. "Briann was because a week and a half before she was born, one of Casey’s cousins, who he was really close with, passed.

"He was in a car accident. His name was Brian. She's also named after my older brother, Bryan Spears. We just added another 'n' to it and made her Maddie Briann."
