"I've always known that I was going to have a baby one day. But there's times when I get a little scared. It's mind-blowing to have a child," Spears, who has put her career on hold to await the birth of her first child with husband Kevin Federline, tells Elle magazine in its October issue.
The therapeutic side of the process, she says, comes from the way "All the secrets from your family come out of the closet for some reason. But it's good. They have to come out sometime. You know what I mean?"
Asked what she means by "family secrets" she says: "Right before I met Kevin, I didn't talk much. I got kind of introverted. Being an entertainer, especially starting at such a young age, you long to please people and become what they want to see. In the last two years I've totally gotten out of that."
As for the gender of the expected arrival, she thinks it’s a boy but isn't sure.
Spears also says she's nervous about giving birth because "I don't want to go through the pain. My mom said giving birth was the most excruciating thing she's ever gone through in her life."
