How good of friends are you? I would do as babygap said and in a mature and maybe even joking way bring it up. She may have just been "picking" on you because you are friends and assumes you think nothing of it. On the other hand if she does feel these things are true like babygap said she should have talked to you in private. I know your feelings are hurt, mine would be too. I hope you talk to her and get this straightened out so that it doesn't have to bother you anymore.
