Britney Spears' little sister Jamie Lynn is pregnant.
Jamie Lynn, 16, confirms the pregnancy to OK! magazine and says that she's "shocked." She is 12 weeks along.
According to the magazine, the father of the baby is Jamie Lynn's longtime boyfriend, Casey Aldridge, 19.
She says she didn't tell anyone about the pregnancy for two weeks, then finally broke the news to her mother, Lynne, before Thanksgiving.
Jamie Lynn is best known for starring in the Nickelodeon series "Zoey 101." Last year, she won a Nickelodeon Kids' Choice Award for best Female TV Star and best TV Female Actress.
In a statement to "Extra," Nickelodeon officials said, "We respect Jamie Lynn's decision to take responsibility in this sensitive and personal situation. We know this is a very difficult time for her and her family, and our primary concern right now is for Jamie Lynn's well-being."
Now Jamie Lynn has a message to her young fans about premarital sex.
"I definitely don't think it's something you should do; it's better to wait," she tells the magazine. "But I can't be judgmental because it's a position I put myself in."
