According to TV Guide, Hudson will play a NYADA dance instructor. "Dance is not Rachel's strong point, but as a freshman it's a requirement class she has to take," Lea Michele said. "It will put Rachel in a very vulnerable place, stuck with a teacher who doesn't make it easy for her."
Meanwhile, Sarah Jessica Parker will play a "manager of sorts" to Chris Colfer's character, Kurt. However, it's not in the performance arena.
