Are there any books/series like "The Clique" but for older girls?

I used to love "The Clique" books by Lisi Harrison, I read all of them. But I've kinda out grown them. What are some books like the clique books, but more for a high schooler then a middle schooler? I love books about high school drama, catty, backstabbing, yeah.. I don't know why I like them but I do. Any ideas?
