i think that most teen girls look at celebrities and see that you aren't worth jack if your not a size 2 and they put pressure on girls to have sex because the teen boys are seeing the sexy music videos and the "cool" rappers only sing about sex so i'd say that they have a big influence but there are exception to every rule
Miley cyrus her and her clothes now all little girls are dresses and acting like hannah! i heard a mom say her daughters wearing dresses that are way to short and belly shirts cause hannah is!!!
same with hsm. now every fricken little kid singing and acting like them! so annoying!
