Jamie Lynn Spears, Britney's sister, is pregnant, the 16-year-old told OK! magazine. The father is her longtime boyfriend, Casey Aldridge, she said. "It was a shock for both of us, so unexpected," Jamie Lynn Spears, who is 12 weeks along in her pregnancy, told the magazine for its new issue, which hits stands this week.

"I was in complete and total shock, and so was he. ... As soon as I found out for sure from the doctor, I took two weeks to myself where I didn't tell anybody. Only one of my friends knew because I needed to work out what I would do for myself before I let anyone's opinion affect my decision. Then I told my parents and my friends. I was scared, but I had to do what was right for me."

Jamie Lynn's mother, Lynne Spears, also commented on the news, saying her daughter "was very upset because it wasn't what she expected at all. A week after, she had time to cope with it and became very supportive. ... I didn't believe it because Jamie Lynn's always been so conscientious. She's never late for her curfew. I was in shock. I mean, this is my 16-year-old baby."

Jamie Lynn reportedly plans to raise the baby in Louisiana, her home state, "so it can have a normal family life." In regards to the third season of her Nickelodeon show, "Zoey 101," which wraps January 4, Jamie Lynn said: "I haven't spoken to [Nickelodeon] personally, but they have always been so great to me over the past years and have given me so many opportunities."

When the magazine reportedly asked her about the message her pregnancy might send to you people, she replied, "I definitely don't think it's something you should do; it's better to wait. But I can't be judgmental because it's a position I put myself in."
