Can you believe it? Glee Season 3 is almost at an end. The show is currently taping its second-to-last episode — the as-yet untitled Episode 21 Nationals competition — at the Cal State Los Angeles campus.

TooFab has sources on-set for the taping, and they’re revealing plenty of juicy scoop about what to expect. First of all, there’s the matter of what songs we’ll hear at the competition:

The New Directions will sing:
- Lady Gaga’s “Edge of Glory” performed by Santana (Naya Rivera), Quinn (Dianna Agron), Brittany (Heather Morris), Sugar (Vanessa Lengies) and Tina (Jenna Ushkowitz
- Celine Dion's "It's All Coming Back To Me Now," performed by Rachel (Lea Michele)
- Meat Loaf's "Paradise By the Dashboard Light," performed by everyone 

Vocal Adrenaline, led by Alex Newell (Wade), will sing:
- Nicki Minaj’s “Starships”
- The Who’s “Pinball Wizards”

TooFab’s sources report that Alex will be leading both numbers... while dressed in drag. Unique is back!

(Amazon.com song listings also include grouplove's "Tongue Tied" and Queen's "We Are The Champions" as being included in this episode, as well. Unfortunately, there's no mention of who will be singing which song. It's too bad, too — we get the feeling that learning the identity of the group that sings "We Are The Champions" could potentially be a major spoiler!)

In other big news, it appears that Quinn really will be back on two feet for the Nationals competition. According to TooFab, there is no wheelchair in sight, and Quinn is back to her happily dancing self!

Celebrity guest judges Perez Hilton and Rex Lee were both present at the taping, though the third judge — Lindsay Lohan — was scheduled to shoot some minor reaction shots, but had yet to show up at the time TooFab published their story.

TMZ reports that Lindsay’s main scenes, which she shot a few days ago, went off without a hitch, and that the actress was “very professional.” So one out of two ain’t bad, right?

Now, on to the question everybody really wants to know: Which team ultimately wins the competition? Unfortunately, we’re still going to have to just wait and see. Glee actually filmed two separate endings, and we have no idea which one they’ll use in the final show.

Let the speculation begin!
