The duo starred in the cult 1989 comedy about four girls who form a clique at a suburban high school, and rumors of a follow-up film have been circulating for months.
Now Ryder has confirmed she will be revisiting Westerberg High once more, although the project is so secret, even she's struggling to find out more details.
She tells Empire magazine, "Whatever you hear, there is a sequel in the works, I swear to God.
"But for some reason the writer, Dan Waters, and director, Michael Lehman, don't want to talk about it. I've been wanting to do a sequel forever. There is a story, and Christian has agreed to come back."
