Glee 100th episodeThe most anticipated episode of the fifth season of Glee is almost here. Ok, maybe the 100th episode of Glee is the second-most anticipated -- after the tribute to Cory Monteith -- but the reunion of the show's original cast, save for Cory, is all Gleeks have been buzzing about for months. What's going to happen when everyone comes back to the choir room?

We've got some spoilers coming at you ... along with pictures from the actual episode! From a Brittana reunion to the return of Quinn Fabray (yes, Dianna Agron is finally back) and the debut of a new character played by Gossip Girl's Chace Crawford, the 100th episode is going to be huge.

Songs are expected to include a cover of Pharrell's "Happy" and P!nk's "Raise Your Glass," and there will be plenty of star power for the special episode on Tuesday, March 18. Check out all the pictures for the scoop!

Number #6 shocked us, how about you?
