I would say that you know they are talking about you and that you have plenty of friends and don't need a friend like that in your group.
they say he is a backstabber.
tell your friend about it if she doesnt believe you tell a teacher
because they have nothing better to do!
Your friend has a right to choose who she sees, but it would be to your best interest to not tell your best friend anything that you do not want to have gossiped about. Your friend has to find out for herself that her new friend is a backstabber. Good friends are loyal (such as yourself) and waiting for your best friend to drop the new friend is the best thing to do.
