Britney has a baby name and special day all planned out for her new arrival. She is planning to honor her parents by combining their names, Jamie and Lynn, to create her daughters name Jailynn. We know Jamie Lynn is her sister's name so this family likes to try to keep things easy for everyone to remember. We also hear her daughter will share Sean Preston's birthday. Lowdown reports she is planning a C-section for next Thursday, September 14th! That should make it really easy for Kevin to remember.
