Looks like the easiest way for TV executives to boost ratings on their TV shows is to find the youngest girl they can and make her pregnant.

That's what has happened with Jamie Lynn Spears' Nickelodeon show Zoey 101. The just-broadcast season finale of Zoey 101 - the first episode since Jamie Lynn Spears announced her pregnancy - recorded viewing figures twice as high as usual.

Special mention should be given to the lucrative Dirty Old Middle-Aged Men demographic, which we imagine has gone sky high since Jamie Lynn Spears revealed that she was sexually active.

Before she decided to make the leap into becoming a professional pregnant schoolgirl, Jamie Lynn Spears was best known for her Nickelodeon TV show Zoey 101.

OK, that's not exactly right - Jamie Lynn Spears was best known for being Britney Spears' sister, then for being in a film where she played Britney Spears' sister, then for being Britney Spears' sister in a TV show about Britney Spears, then for being Kevin Federline's sister-in-law and then for her Nickelodeon TV show Zoey 101. Not that any of that means much any more, because it's been reported that Nickelodeon has dropped Zoey 101 thanks to Jamie Lynn's pregnancy. Heaven knows why, because we always thought that children's TV badly needed a teen sitcom about a schoolgirl with postnatal depression so severe that she routinely fantasises about dropping it out of a window. Or something.

If Jamie Lynn Spears' life was an episode of Maury - which it isn't, yet - it'd probably be called I'm A Pregnant Teenager And My Boyfriend Cheated On Me Even Though I Don't Know If He's The Father Or Not Yet.

Because, keen to make sure she lives up to the staggering level of personal ineptitude that her big sister is so fond of, Jamie Lynn Spears is determined to make her pregnancy one of the worst stage-managed in all of history. We've already had the outrage about Jamie Lynn Spears getting pregnant at 16, then the outrage about statutory rape, and now it's time for some fresh outrage, this time about the way that Jamie Lynn Spears' boyfriend Casey Aldridge is a 'lying cheating dog' who can't stop getting other girls pregnant. Not enough for you? OK, well what about Jamie Lynn Spears not knowing if Casey Aldridge is actually the father of her baby anyway? Better? Thought so.

The shock pregnancy of 16-year-old Jamie Lynn Spears has shocked all kinds of reactions of people, be it sadness, anger or - in the case of all grubby old men - vaguely muttered sexual arousal.

But Jamie Lynn Spears needs support in this difficult time, and who better to give it to her than everyone's favourite overbearing soul diva with ideas half a notch above her station Mary J Blige. While the rest of the world tuts in disapproval and mumbles things like "terrible parenting," "statutory rape" and - in the case of all grubby old men - "haven't you been a dirty girl?" Mary J Blige is there for Jamie Lynn Spears, snapping her fingers, popping her neck and representing for the sisterhood so hard that it looks like she's having some kind of bloody seizure.

Creepy sterile men, form an orderly queue - Jamie Lynn Spears, the newly-pregnant 16-year-old sister of Britney Spears, might very well be back on the market.

Less than 24 hours after Jamie Lynn Spears announced to the world via OK! magazine that a boy she met at church had knocked her up, it's looking increasingly like the pregnancy has driven a wedge between her and the baby's father Casey Aldridge. Yesterday Casey Aldridge took to his MySpace page to poetically express the profound complexity of young love torn asunder by sudden biological maturity. In other words, Casey changed his mood to 'Blah' and listed his status as 'Me and Jamie are over :('. It's hard to know how Jamie Lynn Spears will react to such a poignant display of heartbreak, although experts are guessing it'll either be :'( or x_x depending on how heavily the hormones are kicking in.

You have to hand it to Jamie Lynn Spears - not many 16-year-old girls would try and take the heat off their messed-up older sisters by getting themselves pregnant at a ridiculously young age.

But that's just the kind of socially-conscientious girl Jamie Lynn Spears is. Now that her older sister Britney Spears is being heralded by many as the world's most famous bad mother, Jamie Lynn wants to have a go, too - so she's announced to the world via OK! magazine that she's 12 weeks pregnant with a baby fathered by her long-term boyfriend Casey Aldridge. News of Jamie Lynn Spears' pregnancy might seem like the Spears family has now reached critical mass when it comes to sexual irresponsibility, but you haven't seen anything yet - the cover of next week's Us Weekly consists of a close-up photo of baby Sean Preston's face alongside the quote "Dude! I Totally Knocked Up 15 Thai Sluts Last Week!"
