It’s a girl for Jamie Lynn Spears!

Lynne Spears isn’t thrilled that her youngest daughter is pregnant at 17. But she was delighted to go along with Jamie Lynn to learn the baby’s gender — and discover she’s finally going to have a granddaughter!

And she wasn’t the only one happy with the news. “I heard Lynne talking about Jamie Lynn’s baby,” says a witness. “She said Jamie Lynn and the baby’s dad [Casey Aldridge] were so excited when they found out it’s a girl.”

Though the witness overheard Lynne, 52, say Casey, 19, is “a bit nervous about having a daughter,” Jamie Lynn is eagerly prepping for the arrival of her mini-me. “She has been buying tons of clothes and is going to do the nursery in white, black and yellow,” says a Spears family insider — who also reveals that the baby is due on June 29.

Of course, Jamie Lynn has much more on her mind than just decorating — like figuring out what to call her baby girl. “Lynne said Jamie Lynn made a list of all the girl family names on both sides of the family and is trying to incorporate one of them as the middle name,” says the witness, who also overheard that “Lynne’s flattered to hear her name is being considered.”
