What is it with the Spears family?

Jamie Lynn is pregnant, and she’s just 16 years old. Her family’s shocked. “She’s usually so conscientious,” says her mother, who still can’t over how her “baby” is going to be a mom.

Jamie stars in Zooey 101, one of the top rating shows in Nickelodeon. This family-centered station, who’s probably reeling at the PR disaster that’s unfolding before its eyes, simply 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.”

Jamie is 3 months pregnant. She found out through a pregnancy test, then went to a doctor’s appointment. She and “longtime” boyfriend Casey Aldridge (how long time can it be when she’s just 16? They’ve been dating since she was 12???) kept it secret for 2 weeks.

“I needed to work out what I would do for myself before I let anyone’s opinion affect my decision,” she told the magazine.
