'Glee' Welcomes An Old Friend And New Face For 100th Episode: Find Out Who

Gwyneth Paltrow will reprise her role of Holly Holiday and will be joined by a 'Gossip Girl' vet.

Gwyneth Paltrow is ready to bring some song and dance to the small screen again. The Oscar-winner has been confirmed to appear on the upcoming 100th episode of "Glee." She will be joined by "Glee" newcomer Chace Crawford during the milestone episode.

According to E! News, she will reprise her role of Holly Holiday during the two-part special, which will air March 18 and March 25. Paltrow won an Emmy for her guest spot on the Fox sitcom in 2011.

The site also reports that Crawford, according to Matthew Morrison, will likely play a love interest for Dianna Agron's character. Morrison teased, "His name is Biff. He's kind of a Yalie degenerate."

Among the crew set to return are Agron (Quinn), Heather Morris (Brittany S. Pierce), Harry Shum Jr. (Mike), Amber Riley (Mercedes) and Mark Salling (Puck).

According to The Hollywood Reporter, the episode will find Principal Sue Sylvester shutting down the "Glee" club for good. New Directions, past and present, will come to Lima to say goodbye to head Gleek, Will Schuester (though Morrison is not leaving the series), in the wake of the shutdown. From there, the show will settle into NYC for a handful of episodes.

The 100th episode will include remixes of songs that previously appeared on the series.

MTV News spoke to star Lea Michele last month about what tracks she's most excited to reprise. "There were some performances that were so difficult and I see it happening. I see myself putting on those goulashes again to do 'Singing in the Rain,' " she said of the track, which the cast, including Paltrow, performed in 2010 as a mash-up with Rihanna's "Umbrella." "And I'm like 'Oh my god, please don't make us do that again!' We were so cold, we were freezing."

And, there's even one song the "Cannonball" singer would love to tackle again, even if it's emotional.

"If I could do anything again, the thing is that some of them are very emotional but I'm the kind of person I don't run away from my feelings, I don't run from things that scare me," she said. "I want to feel all the emotion and so to be surrounded by the cast and sing something like [Queen's] 'Somebody to Love.' As hard as that might be, I think that, it just brings back some of the most amazing memories of someone [Cory Monteith, who died in July] who we loved so much and it's numbers like that I hope we do."

Ahead of the 100th episode, "Glee" returns on February 25.
