For the landmark 100th episode, Chace Crawford will appear on 'Glee' as Dianna Agron's love interest.
The former 'Gossip Girl' star is confirmed to be casted as Quinn Fabray's beau. According to Mirror UK, cast regular Matthew Morrison confirmed the report, saying, "I think he's going to be Dianna Agron's new love interest. His name is Biff. He's kind of a Yalie degenerate."
But Chace won't be the only special guest. Actress Gwyneth Paltrow is also rumored to reprise her role as Holly Holiday, the substitute teacher at McKinley High. Kristin Chenoweth, who appeared as April Rhodes has also been confirmed to make an appearance.
The milestone of an episode, according to EntertainmentWise, will feature a disbandment of the Glee Club after Jane Lynch's character, Sue Sylvester, destroys the New Directions. Future episodes will then be based in New York, where the storyline will focus on key characters, including Rachel Berry (played by Lea Michele).
The future of 'Glee' was toppled after the death of one of its key characters, Finn Hudson (played by the late Cory Monteith). However, in an interview with screenwriter Ryan Murphy, he said that the conclusion to the popular series was already formed in his mind.
Murphy previously told E! Online
The ending of Glee is something I have never shared with anyone, but I always knew it. I've always relied on it as a source of comfort, a North Star.
At the end of season six, Lea's Rachel was going to have become a big Broadway star, the role she was born to play.
Finn was going to have become a teacher, settled down happily in Ohio, at peace with his choice and no longer feeling like a Lima loser.
The very last line of dialogue was going to be this: Rachel comes back to Ohio, fulfilled and yet not, and walks into Finn's glee club.
'What are you doing?' he would ask.
'I'm home,' she would reply. Fade out. The end.
The 100th Episode will air in the US on March 14.
