How can I convince my best friend that I'm being framed?

My BFF is starting to hate me. She just told me that someone told her that I said that I liked the guy she likes and that I said I would have a better chance before her but I never said that and I don't think she is believing me and I think the girl that she used to be best friends with they started talking again and she doesn't like me. I think she might be framing me to get my BFF mad at me. What do I do? any advice please HELP ME!

If she was really your BFF she would know you didn't say that.
