Dad doubted Jamie Lynn's legitimacy

Problems in the household of Britney Spears have now got never-ending! As big sis, Britney fights against the 'bipolar disorder' in hospital, younger sister Jamie Lynn has another problem to face. The 16-year-old who prepares to become a young mom is shattered with the family secret leaked out by their uncle, William Spears, who says that the teen Jamie's own birth was reportedly unplanned, and her father had demanded a paternity test to make sure he was the baby's dad.

According to him, Lynn's father had gone through a vasectomy after the couple's second child. Uncle Willie says, "Jamie got awfully mad. He said it couldn't be his." William Spears alleges his big brother then demanded a DNA test that proved he was the baby's biological father. He adds, "That's why they named her Jamie Lynn, to kind of make the point that she was from both of them."
