This chart reveals the thrust of more than 100 of the most recent headlines for stories on "Jamie Lynn Spears." Even though a hearty 12 percent of headlines were generic announcements of her being impregnated, 15 percent were comments about her getting knocked up as Brit's sister.

Some highlights:

TMZ interviewed Uncle Odus:

He tells us the family was "shocked' and yet "we aren't." As a pastor, Uncle Odus says he's seen "this type of thing" more often than he'd like.

Papa Bear O'Lielly added her to the pinhead club:

On the pinhead front, 16-year-old Jamie Lynn Spears is pregnant. The sister of Britney says she is shocked. I bet. Now most teens are pinheads in some ways. But here the blame falls primarily on the parents of the girl, who obviously have little control over her or even over Britney Spears. Look at the way she behaves.

But Mary J. Blige was there to offer support:

"Stay strong, baby girl. If that's her choice (to keep the baby) then congratulations. Hope she's responsible and I hope she understands what that brings.

So what's older brother Bryan Spears up to these days?
