Uncle claims Jamie Lynn was an accident

William Spears, the brother of Britney and Jamie Lynn Spears's father Jamie, has claimed that the Zoey 101 star was an accident, reports The Sun.

William, who lives in a camper van, said Jamie was shocked when his wife Lynne told him she was pregnant as he had undergone a vasectomy after the birth of Britney.

He said: "Jamie got awfully mad. He said it couldn't be his."

Jamie allegedly demanded a DNA test, which proved he was Jamie Lynn's father.

"That's why they named her Jamie Lynn, to kind of make the point that she was from both of them," William added.

Jamie Lynn, 16, announced she was pregnant last December by boyfriend Casey Aldridge. However, rumours surfaced claiming that Aldridge wasn't the child's father and that he was being paid to cover up the identity of an older man, who could face criminal charges for sleeping with Jamie Lynn.
