Probably Jackson and Timberlake will admit they didn't want to do it...that it was in their contract and HAD to.
This is why I hate TV. Some guy behind a desk who thinks that the US is full of uneducated slobs who love to see this kind of Britney Spears half naked teen angst put to terrible music.
It is either a terrible insulting misjudgement on the minds of Americans, or it is a sad truth about what the people who watch tv really like. I would hate to know either way.
According to the LA Times, entertainment reporter Pat O'Brien interviewed Justin Timberlake right after the incident. Justin said he did it to "give people something to talk about." Of course, he changed his story quickly enough to a "wardrobe malfunction" as soon as the firestorm started!
