Should I cut my hair?

I know you're thinking why do I have a picture of Posh Spice on my blog, right? I've been thinking about chopping my hair off and cutting it like hers. If you're in my family you may remember Katy had hers cut like this. Look to the left of the page and you can vote. If you can, leave a comment and tell me what you voted.
Mine would be slightly longer and much thicker than the one below. But I wanted you to see a back shot.
