After reading everything to do with the Spears family, I have realised that everyone in that family is going nuts due to fame forced on them when they weren't ready. After all, both siblings were child stars, and look at them now.
Quote from YouTube rant about Britney:
"OMG - [Jamie Lynn]'s got the brain of Britney! She shares a brain with Britney! OMGZ my hair's gonna fall off - oh wait, it already has, never mind."
