Would you remain friends with someone like this?

I have a new friend, and she was SUPER nice at first. Which is what attracted me to becoming her friend and getting close with her. I’ve noticed over the few years of being close with her, she has mean girl tendencies. Like for example, her cousin got a girlfriend, and she kept telling me how she thinks she’s ugly while the girl was feet away from us. Mind you, she wasn’t ugly at all to me. Not just this but she always mentions how she thinks girls she knows are ugly. She also does my waxes on my legs, armpits, you name it, and she because I went to another waxer, she got mad at me and tells me they do a butchered job, when I know they do a good job!! The fact that she’s an undercover mean girl just doesn’t sit right with me, and I can’t go against her or she gets mad.
