hilary duff

a disney channel star that isn't that good at singing but has made it through to the real world outside of disney without going to rehab, making a sex tape, attacking the papparazi, or sent naked pics to her boyfriend, only to have them leaked all over the internet. in fact you rarely ever hear of her at all.

i would say hilary duff's just chill, neutral even. but her voice still sucks o.O
