Condomnation For the Britney Spears Clan

This just in: Teenaged girls have sex. And sometimes they get pregnant.

Don't tell the abstinence-only crowd at the White House, but these disturbing realities led to serial embarrassments this week for the family of Mother of the Year contender Britney Spears.

First, it was revealed that the pop tart's scandal-free 16-year old sister Jamie Lynn, the star of Nickelodeon’s hit "Zoey 101" show, is three months pregnant.

Father-to-be Casey Aldridge, 19, could face a statutory rape charge because knocking up anyone under 17 is considered "felony carnal knowledge of a juvenile" in their home state of Louisiana.

Jamie Lynn's father is "furious" that she sold the story of her pregnancy to OK! magazine, while Britney is "frantic" about the whole mess and not at all pleased that Kevin "Fed Ex" Federline, her former husband, was told first.

If that wasn't bad enough, there is the beyond crushing news that mother Lynne Spears' forthcoming book on parenting, Pop Culture Mom: A Real Story of Fame and Family in a Tabloid World, has been put on ice by Thomas Nelson, who publishes inspirational books and Bibles.

Janice Min, veteran celebrity watcher and editor of US Weekly, huffed: "To have a woman preparing to write a book about how to raise daughters when her own two daughters are imploding reeks of incredible denial and a lack of self-awareness."
