Jamie Lynn Spears a mum

Jamie Lynn Spears has become a mother for the first time after giving birth to a baby girl.

The 17-year-old actress, younger sister of troubled singer Britney Spears, had 7lb 11oz Maddie Briann yesterday morning (19.06.08) at a Mississippi hospital.

Both mother and baby are doing well after Jamie Lynn's natural delivery. During the labour at Mississippi Southwest Regional Medical Center, Jamie Lynn was joined by her mother Lynne and fiance Casey Aldridge, while mother-of-two Britney waited anxiously outside.

A source said: "Just the family was there. Everyone is healthy and happy. Maddie is gorgeous."

Casey, 19, was said to be nervous about holding his baby daughter for the first time as he thought he was going to drop her. Friends insist the 'Zoey 101' actress will make a fantastic mother.

One said: "We're so excited for her. She'll be a great mom. She'll be awesome. She was so excited about having this child. She was looking forward to it so much."

Earlier in the week, Britney had flown to Kentwood, Louisiana, from her Hollywood home to be with sister. Jamie Lynn announced her pregnancy last December and admitted it was a shock but was looking forward to becoming a mother.
