Jamie Lynn Spears is pregnant again, just three months after giving birth to her first child - according to U.S. tabloid reports.
The 17-year-old sister of pop superstar Britney Spears shocked the world when she announced last December (07) she was expecting a child with her boyfriend Casey Aldridge.
She welcomed daughter Maddie on 19 June (08) - and the National Enquirer claims she conceived a second baby with Aldridge just four weeks later.
A source tells the magazine, "Jamie Lynn believed she couldn't get pregnant while she was breast-feeding. She'd expected to have her period by early September. When she didn't, she told a family member."
The teenager reportedly then took a home pregnancy test, which came back positive.
The insider adds, "When the test came back positive Jamie Lynn cried her eyes out. She realises how dumb she looks for getting pregnant again so soon."
The source claims Spears has yet to tell Aldridge, with whom she has an on-off relationship, adding, "Jamie Lynn is about eight weeks pregnant, and she and her mum Lynne are hysterical. Neither of them knows what to do, but for now they're trying to keep the news from getting out."
A representative for Spears could not be reached to confirm the reports as WENN went to press.
