Britney Spears was said to be shocked when she heard along with the rest of the world that her 16 year-old sister, Jamie Lynn, was pregnant. She even told a paparazzo who asked her about it that “my sister’s not pregnant,” while looking mildly amused at the question. People Magazine reports that a friend claims it will be a big shock to her and that another insider says that Jamie Lynn and Britney haven’t seen much of each other and that Jamie Lynn’s people have tried to keep them separated.

The pregnancy is definitely confirmed, with Jamie Lynn and her mom, Lynne, speaking directly to OK! Magazine. Nickelodeon Network, which carries Jamie Lynn’s television show “Zooey 101,” issued the following noncommittal statement about Jamie Lynn’s pregnancy and the future of her show:

“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.”

Jamie Lynn says her pregnancy was “so unexpected” and a “total shock,” but doesn’t she know where babies come from? She was living with her 19 year-old boyfriend and her sister has two children she gets to see only under court supervision. Surely someone should have had a talk with her about using contraceptives. Her mom’s parenting book is on hold after this scandal and I’m guessing there wasn’t a chapter in there about teaching sexual responsibility.

There was a story in July that Jamie Lynn had a pregnancy scare, so unless she’s further along than she claims she had ample warning that she needed to go on the pill or use another method if she didn’t want to get pregnant. I’m not saying it’s all her fault – her boyfriend should have been using something too, but they both knew what they were getting into by having unprotected sex.

Back in July, the story was that Britney told Jamie Lynn to “use condoms,” but she seems to have followed Britney’s behavior rather than her advice and has found herself in a precarious situation. Jamie Lynn also was said to have told Britney first that she thought she was pregnant. That wasn’t the case this time, and Britney had to find out from the tabloids along with the rest of us.

Let’s just hope that Britney realizes this is the time to focus on her own children rather than freak out about her sister, who still seems more mature and capable than she does, although that could change rapidly for her.
