Glee Stars Dish on Tonight's Emotional (What?!) Lady Gaga Episode

Adam Rose/FOX

If you happen to be one of the lucky ones who's seen the Glee Live concert (hint: It's so good, I literally lost my voice screaming!), you know that there is very good reason to tune in to Glee tonight: Lady Gaga.

The costumes, the bubbles, the songs, the stuffed animals the…tears?! Wait a minute, what? Again?! Here's the scoop:

Chris Colfer (Kurt) tells my pal Korbi that he shot a scene that is the most emotional scene ever on the series. And with the recent waterworks of the past few episodes, that is saying something!

"It was pretty intense," Chris say of his scene tonight with Mike O'Malley (Kurt's father) and Cory Monteith (Finn). "I kind of realized, Oh there's such a bigger meaning behind this! Omigod, this is so dramatic."

And Chris isn't the only one OMGing. Heather Morris (Brittany)—who pretty much steals the show at the Glee Live concert, BTW—tells me of tonight's episode: "Oh, god. You have no idea. It's so good! I can't wait for everybody to see it and like our outfits and everything. Naya and me, we have the most insane outfits. It's awesome."

"Lady Gaga's person made our costumes," boss Ryan Murphy tells me. "It's, I think, our most expensive number because the set is crazy and the costumes are crazy. And we like to keep it real, so Lea and Idina Menzel do an acoustic version of "Poker Face" that she blessed and wanted us to do. Sort of like a stripped-down mother/daughter 'Poker Face' that Lady Gaga was involved in."

"It's really nice and we do these cool harmonies," Idina tells me of the duet with Lea. "I guess the meaning of the song, which is quite sexual apparently, is different within the context of the show. It's actually very simple and truthful."

Speaking of the mother-daughter twist, any chance now that since Mr. Shue has made out with Shelby (Idina Menzel) and Shelby is Rachel's biomom, they all might end up one big happy (second) family?

"No, I don't think Will is going to end up being Rachel's stepdad or anything," Matthew Morrison (Will Schuester) tells me with a laugh. "That was a big twist with Idina's character. I just loved that episode. It was fun."

And, of course, it's not all Gaga tonight. "We are in KISS costumes," Cory Monteith (Finn) tells me. "I'm all Finn and I'm all like, 'Mr. Schue, we're guys. We can't do Gaga. The only guy who's gonna wanna do that is Kurt. But I don't want to.' So, I suggest KISS and it happens. It's better than Pantera!"

Tune in tonight for all the Glee Gaga goodness!
