Here is a quote from Jamie Lynn Spears which she uttered in an interview with OK Magazine:

"It was a shock for both of us, so unexpected. I was in complete and total shock and so was he"

OK, she was in shock.  Should you have really been in shock?  Is it really that unexpected?  First, you have sex, and second, it was probably unprotected.  How can you be shocked when you find out you're pregnant?  Although, what would you expect from someone who is too stupid to realize that she had a pretty good life going, then gets pregnant.  By the way, save your criticisms, she's an idiot.  That's the only word I can use to describe someone who seems to have a successful career acting in a children's story.  Her career won't be as resilient as her sister's.  Where as Britney's sluty/self-destructive behavior seems to fit in with her persona, Jamie Lynn's revolves on being a squeaky clean star of a kid's show.  Hey Jamie, let us know what the unemployment line is like!
