Hav U Guyz Heard Of Model Search America?HELP

I was talking to my friend and she was telling me that tomorrow she was gonna go to this Model Search. And she was all like "Why dont u come?" And i was like "ok". She said that I should go because im "skinny". But I dont think that I have the right "look". Im female, brown eyes, medium brown hair, weigh around 95 lbs., my height is only 5ft! Im 13 years old about to turn 14 in April. And eventhough Im mexican I have pale skin! (THANX TO MY GREAT GRANDFATHER!). And I think my friend is cuter than me plus she has had modeling experience (just alittle). My friend has light brown hair, it looks like tanned skin, big eyes (my eyes are kinda big too), she`s a good height and a nice build. I think Im gonna go with her but I feel insecure and nervous cuz I`VE NEVER DONE THIS BEFORE!
