Honestly, I think you shouldn't be friends with a person just because they are popular. Before agreeing to be friends with a person, you need to know they are a true friend. As for your other friend, you should try telling her if she is annoying you and what she's doing. If she is a good friend, she shouldn't get annoyed with you for saying that but understand and try to stop.
Good luck
