People say I'm spoiled but I'm really not?

This girl at my school is one of my friends. Except she only sometimes is a good friend if you know what I mean. Last year, she wasn't talking to me and reading my texts but not replying. I asked her at school what was up and she said "I'm mad at you." I asked why and she simply replied "'Cause you're a spoiled brat."
I don't know what happened, but now a lot of people think I'm spoiled! I think she went around telling everyone but I'm not sure. I'm not going to be like those other spoiled questions and name everything I have. To be honest, I don't have much. The only expensive thing I have is the iPhone 6s and I still have to wait a few months before I get it. I don't know where she got the idea that I'm spoiled! I'm afraid I'll get a spoiled reputation because of this rumor! How can I get her to stop making up stuff? Please help!

Added (1). And no, I'm not bratty about the stuff I get. I'm very thankful for the things I have!

White women are the most spoiled trash in america

They are just too

Don't waste your time over what others said about you. They're preventing you from reaching your destiny.

Best thing is to stay away from her, and anyone who believes bad things she says about you. If anyone brings it up to you, don't act like you even take it seriously, just say I don't know what's up with that stupid rumor.
