EXCLUSIVE 'Glee' Sneak Peek: Brittana is Getting Married and We're Freaking Out!

You are cordially invited to attend the wedding of Miss Santana Lopez and Miss Brittany S. Pierce on Friday, Feb. 20 at 9 p.m. on Fox.

You are cordially invited to attend the wedding of Miss Santana Lopez (Naya Rivera) and Miss Brittany S. Pierce (Heather Morris) on Friday, Feb. 20 at 9 p.m. on Fox.

We hope you'll RSVP because wedding bells are ringing on Glee, and only ETonline has your exclusive sneak peek of the gorgeous location and reception! Plus, we've got your first look at all of the special guest stars who have also been invited to attend -- and sing at! -- the lavish affair.

One of our all-time favorite characters, Sugar Motta (Vanessa Lengies), is known for disappearing from the choir room for months at a time without any explanation whatsoever. But did you also know that that there is a fan-favorite theory our there in the Tumblrverse for why this keeps happening? (Of course you do, you're Brittana fans!)

"I love being back it's like a big family reunion," Lengies explains to the cameras with a huge smile alongside Harry Shum Jr. "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."

Not only is Brittany and Santana's "daughter" making an appearance on their big day, this star-studded event going to feature some of Lima's coolest parents. Santana's mom (Gloria Estefan) will support her daughter, Brittany's outrageously awesome mom and dad, played by Jennifer Coolidge and Ken Jeong, will also be there, and for the first time, fans will finally get to meet Blaine's (Darren Criss) mom, played by the lovely Gina Gershon.

And prepare to soon, Brittana babes, because we've got your first look at Santana and Brittany ultra-romantic, pre-wedding conversation!

"Do you even know why the groom couldn't see the bride before the wedding?" Santana asks Brittany in the moments just before they're set to say, 'I do.' "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."

"But that's not us, okay?" Santana tells her blushing bride. "Because you love me and I love you." 

And if that didn't already convince you, get ready for the most romantic episode in Glee's history. We at ETonline sworn to secrecy and cannot reveal some of the heart-melting twists, but according to Lengies, there's some "rehashing of some old romance" in this week's hour, so make sure you have plenty of tissues on hand.
