I had an argument with a friend, shes apologised but is still lying?

Me and a group of friends had a big disagreement with a friend, and last night she rang me apologising, telling me that she would love it if we could be friends again. I was wary, and had a right to be - earlier on in the day she had told another one of my friends that me and her had been speaking weeks ago over msn, basically stirring up the argument again and making it look as though I'm on her side - its clear that none of my group of friends have spoken to her since the disagreement. I'm so angry that she would have the cheek to want to be friends again after lying so much, and don't know what to do. The only reason she has apologised is because she has finally realised that she has no one. I would love to confront her about it, but that would be giving her the attention that she craves. Should I bring up the fact that shes lied so blatantly or just ignore it?
