Britney Spears... Just asking?

What do you guys think is going on with Britney Spears? Is it all cause of K-Fed? Postpartum or marriage too soon? Is it cause she was exposed so early by her Mother and never enjoyed much of her childhood but was doomed into the Limelight so early at age? Just want you guy's opinion cause I kinda feel bad for her in a way and seeing her alot on the Headlines!
