ok, so i have seen pics of hayley when she was younger and she had a septum piercing. am i right???

Yes, you are correct. I'm pretty sure she still does have her septum pierced, but maybe the hole closed up? She doesn't really wear it anymore like she used to, in fact I haven't seen her wear a piercing there since BNE came out. Maybe she's grown out of it & just doesn't wear it anymore. IDK. But anyways, you were right.
