With the publication of Lynn Spears´ book come a whole bunch of revelations which pretty much amount to the overall impression that she has the parenting skills of a Las Vegas pimp down on his luck and heavily in debt to the mafia. According to the book, Britney was allowed to sleep with Justin Timberlake (who mistakenly believed he took her teen cherry) when she was a teenager.
The truth of the matter was that she had already lost her virginity to a footballer from Kentucky, and evidently Mamma Spears didn´t believe in bolting the stable door after the horses had fled, but instead declared her daughter a virtual rodeo.
The fact that Jamie Lynn managed to get herself pregnant at sixteen is making a lot more sense now - the fact that Britney wasn´t pregnant at that age isn´t.
