Search Results: no call list

So a while back my friend asked me what jobs I was applying for. I told her and she said she would apply for the same one. I have no issue with this. We are both qualified for the position from past experience. In fact I helped her get the previous job along side me when they were looking for extra help.
My issue is that she doesn't like the organization and has posted crap about it on her social media accounts. I actually like the organization and speak highly of it. However, she recently told me she listed me as a reference and said I was her supervisor. She also changed her previous title to a level higher then it actually was. What makes matters worse is that I submitted my resume and I told the truth about my previous position. If called by an HR rep I feel I have no choice but to decline answering any questions in regards to her. I'm feeling conflicted.
