JAMIE-LYNN SPEARS is desperate to find out the sex of her unborn child, and has begged doctors to tell her as soon as they can.

On Tuesday (18Dec07), 16-year-old Jamie-Lynn revealed she is 12-weeks pregnant with her first child with boyfriend of two-and-a-half years, Casey Aldridge, 18.

And she can’t wait to learn if she is carrying a son or daughter, so she can start shopping for baby clothes.

Jamie-Lynn says, "I want to find out as soon as I can because I’m impatient. I just want a healthy, happy baby, so whether it’s a boy or girl doesn’t really matter. I haven’t thought about baby names yet. I would have to hear some options." The TV star sister of singer Britney also reveals she plans to bring her child up in her native Louisiana, adding, "I definitely want to raise my baby in Louisiana so it can have a normal family life. I want to be able to do the normal things that you are able to do by living in Louisiana."
