First that unexpected gay kiss, now Gwyneth!

Glee continues to be a star-studded affair this season with stars ranging from Britney Spears to Oscar-winner Gwyneth Paltrow. The Country Strong actress - who might win another Academy Award nomination for her latest flick - guest stars on next week's episode of Glee as a substitute teacher who takes over the glee club.

Paltrow is set to perform a medley of "Singin' in the Rain" and "Umbrella," not to mention a tame version of "F*** You."

And that's not all for the movie star! Paltrow will also sit down with Chelsea Handler - along with Anne Hathaway and Christina Aguilera - for Chelsea's Big Interview Special on November 22nd. Can't wait!
