need some serious advice, Two faced friend Options

[stardust57]

A friend of mine had lets call her Brandi and had made some indications that she was interested in my man Joey. Well she hadnt acted on anything so I let it be but then recently Brandi has semed to get a little more flirtatious with Joey and he has made it clear that he doesnt want anything to do with her. Well last night me and joey wanted to see if she was just joking around or serious so we played a little joke on her and joey called herup and told her that we broke up to see what she would say. Well at first she was all like you two have to get back together and then she turned the table and started telling joey to forget about me and that he should come over to her house cause she was horny. then she proceeded to make up a bunch of lies about me trying to deterr him and basicall made me out to be the town whore even giving him names of guys i had never even heard of saying that i had slept with them and then told him how much better she was than me. Im pissed as hell but I don't know how to approach her without ending my ass in jail. Because I want to rip her head off. Any advice on how to handle this?
