Jamie Lynn Spears is pregnant for the second time, it has been claimed. The teenage sister of Britney Spears, who gave birth to her first child just three months ago, is said to have pals urging her to abort the baby, while her mother Lynne is said to be furious.

Jamie Lynn gave birth to daughter Maddie Briann on June 19. Soon afterwards the baby's father, teenage Casey Aldridge was accused of cheating while she was pregnant. She is convinced Casey is the father of the new baby, but has yet to tell him because of troubles in their relationship. 

"Jamie Lynn believed she couldn't get pregnant while she was breast-feeding," said the source. A home pregnancy test came back positive and Jamie Lynn cried her eyes out. "She was afraid to tell her mum because she remembered how frustrated her mum was when she accidentally got pregnant the first time."

It comes as Aldridge told another US celebrity magazine, OK!, that he did not cheat on Jamie Lynn, "that's news to me. In a small town, everybody knows everybody. But when money's involved, you find out who your friends are."
