Someone’s got a nervous habit… or a hangnail! So what, right? A lot of us have to pick at something or chomp off a nail once in a while… But at this point, Britney should know better than to do it out in the open because she’s always being watched. I mean, I guess I can kind of see why she’s so miserable, I would hate it if I could never pick my nose ever again because someone might catch it on camera… but still, she should know better.
