I said my friend is acting like a . what should I do?

I told my friend she was being a faker for saying bad things about one of my other friends then the next day having her over. So she got mad and told me I have no right to talk because I do that too. I told her I never did that and that she was being a bad friend because the only time she ever comes over is to use my computer to talk to older men online, call guys and pretend to be rich to get boyfriends and to wear my stuff that she always breaks or ruins, and she's only 14! Her mom called my mom and cussed us out and now all of my friends hate her and my mom is thinking about moving, what should I do?
