Glee’s epic disco tribute episode — Season 3, Episode 16: “Saturday Night Glee-ver” — won’t air until April 17, but thanks to our favorite (on- and off-screen) couple, we already get a sneak peek at what to expect.

Still-not-officially-official couple Lea Michele (Rachel) and Cory Monteith (Finn) both tweeted behind-the-scenes photos for their fans on Twitter. On February 27, Lea tweeted this fun pic, saying, “Another great disco number in the auditorium with HeMo @DarrenCriss and @iharryshum ....”

And when she says another great number —  it sounds like there have been plenty! Earlier in the day, she tweeted about a sexy new song from Naya Rivera (Santana) to watch out for. “@NayaRivera is killing it in the choir room right now. Singing and rocking it in the sexiest 70s jumper:)”

Back on February 24, it was her guy, Cory, who took to documenting the Glee disco experience on Twitter. During one particularly late night of shooting — 11:54 PM, to be exact — Cory posted this picture of Lea trying to catch a few winks in between takes. “Midnight on the set of glee,” he wrote.

Wake up, Lea. It may be midnight, but there’s dancing to be done! And disco dancing, at that. In fact, rumor has it that The New Directions performance of “You Should Be Dancing" will feature the original illuminated floor graced by the shoes of John Travolta and Co. in the original Saturday Night Fever movie.

Now that’s a dance sequence we can’t wait to see! Is it April 17 yet?
