Glee is celebrating its 100th episode! The hit FOX series will air a two-part 100th episode special on March 18 and 25, and plenty of famous faces will be showing up in the New Directions rehearsal room.
The Hollywood Reporter confirms that Gwyneth Paltrow will reprise her role as substitute teacher Holly Holiday in the episode. But she isn't the only former Lima resident who will be coming back for the very special episode, which (spoiler alert!) centers around the end of the high school glee club.
Former cast members Dianna Agron (Quinn), Mark Salling (Puck), Kristin Chenoweth (April), and Harry Shum, Jr (Mike) are among the familiar faces paying a visit to Lima, Ohio. They'll be joined by Heather Morris (Brittany), who left the show to give birth to her first child, and recent Dancing With the Stars champion Amber Riley (Mercedes).
But there will also be one new face: former Gossip Girl star Chace Crawford! According to Matthew Morrison, who plays glee club leader Mr. Schue, Chace's character is named Biff and is Quinn's boyfriend from Yale.
Although the episode's musical numbers are being kept secret, Harry Shum did give away one big clue: "They’ll be remixing old numbers that we’ve done previously."
Several of the cast members also made cameos in "The Quarterback," an episode which dealt with the on and off-screen loss of Cory Monteith, who played football-star-turned-choir-geek Finn on the series. Cory died of a drug and alcohol overdose shortly before the current season began filming, and the show has had to change several of its major storylines because of his shocking death.
Glee is expected to end after its sixth season next year. There are rumors that lead actress Lea Michele will score her own spinoff as her character Rachel Berry becomes a Broadway star.
