Fox has released a new sneak peek for the next episode of Glee, which features the big Santana (Naya Rivera) and Brittany (Heather Morris) wedding.

'Glee's Brittany & Santana Inspire Kurt And Blaine To Get Married As Well?

The next episode of Glee is appropriately titled A Wedding and features Brittany and Santana's big wedding at a barn. A new sneak peek released through Entertainment Tonight features Harry Shum, Jr. (who plays Mike) and Vanessa Lengies (Sugar) discussing the episode.

"I love being back it's like a big family reunion," Lengies says. "There's a backstory where Sugar is coming back from the future to make sure that her moms are together -- that I'm the future daughter of Brittana. So it actually makes sense if the fan-fiction were to play out, this would be it."

The sneak peek features a scene with Brittany and Santana seeing each other before the wedding.

"Do you even know why the groom couldn't see the bride before the wedding?" Santana asks Brittany. She continues, "It dates back to arranged marriages. People thought that if the couple had time to see each other before the wedding, they would change their minds and bail on actually getting married."

She then explains to Brittany that they love each other so there is really no chance of either of them changing their minds.

Ultimately, Lengies thinks this type of love and acceptance is what has made Glee so great over its six seasons.

"Glee is so special because it celebrated people for their oddities. And I think that just changed people's outlooks on each other and themselves," she says. "Glee brought that all-accepting unconditional love and it spread like wildfire. And I think we're both really lucky to be a part of it."

Glee airs Fridays at 9 p.m. ET/PT on Fox.
