Jamie Lynn Spears On the Road to Becoming Britney With Pregnancy Confirmation

UPDATE: TMZ is reporting that Britney learned of her sister’s pregnancy when word of it hit the media, but that publicly, she is denying the news, having had recently told paparazzi late last night on a shopping expedition definitively, “My sister’s not pregnant!” Reportedly, the rest of the family learned of the news on Thanksgiving, while Brit only just found out Tuesday.

Jamie Lynn Spears has confirmed to OK Magazine that she’s gotten herself knocked up! She told the magazine that the father is Casey Aldridge, who she has been dating for some time and first met at church, and she’s keeping the baby. Nickelodeon (which airs Jamie Lynn’s show “Zoey 101″) issued the following statement this afternoon: “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.”
