The Spears girls have the worst judgment in the history of celebrities.

OK! Magazine is reporting that Jamie Lynn Spears, the supposed “good sister” to a psychotic, dramz addicted older sibling, is, as we speak, 16 and pregnant.

Yup. The Nickelodeon star just confirmed to the mag (and subsequently, the world) that she’s got a bun in the oven courtesy of her “live-in” 19-year-old boyfriend, Casey Aldridge.

This is:

A) horrible news… and

B) even more confirmation that the Spears clan drinks a special kind of water spiked with “bad - decisions - that - will - effect - your - entire - life - and - ruin - your - career” vitamins.

While 10pm on a Tuesday night yields no comment from Nickelodeon, one can only assume that an unwed, pregnant teenager is not exactly the kind of role model they’re looking to endorse, and The Littlest Spears is most likely going to get a front row seat to her own career meltdown.

…That is, unless MTV calls her up and asks her to do a reality series.

“Jamie Lynn Spears: My Life As a Stupid, Pregnant Teenager” anyone?
