I'm glad its not Miley for you but the Jonas Brothers are my role models for lots of reasons, they are down-to-earth, funny, talented, wear purity rings, respect each others, have a strong family base, etc...etc...
i dont have a celebrity role model because i think it is better to have a role model that you can talk to and trust like a family member or friend. you dont know when a celebrity is gunna go do something stupid so its hard to look up to them when their lives are totally different from yours
