It seems to me that Britney deliberately taped everything with the intentions of showing these 'home videos' to the world in another gimmicky publicity stunt to remain in the media, helping boost her sagging music career and jumpstart Kevin's. I'm also assuming a sex tape will eventually surface.
You know, I was thinkin the same thing....because there was one episode where at the top of the screen it says "MAY 2004", and Britney's talking about how Brad Pitt and Jennifer Aniston broke up.....and didnt they break up like in January of 2005? Somewhere earlier this year......so i think all those tapes were filmed deliberately.
She must have filmed them with the intention of turning them in to a show because the whole idea was to make Kevin a celebrity in his own right, instead of just being the loser that left his wife and two kids for another loser that lost her brain and ability to lip-sync when she met him.
