Someone is spreading rumors about me (girl, 7th grade)

Standard

My friend Lori told me that my other friend Amy really does not like me. She said that Amy thinks that I am a show-off during cheer practice and that I try to get all the attention for myself. This does not make sense because Amy and I are good friends. We do cheer together and we talk every day.  Lori thinks that I should stay away from Amy and said that she is doing me a favor by telling me. She does not want me to talk to Amy about it. Lori is my friend so I want to listen to her, but I like Amy too.  I am confused.
