Jamie Lynn Spears Pregnant

A source tells us the interview, which hits stands tomorrow, is six pages and is on the record with Jamie Lynn and her mother. She tells the mag that the father is Casey Aldridge, who she has been dating for some time and first met at church. Brit’s younger sister, star of Nick’s “Zoey 101,” says she’s keeping the baby.

Jamie Lynn said that her mother, Lynne Spears, “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.” Lynne Spears also commented on the news, saying, “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.”
