Watch Now: First Look at Darren Criss Singing Katy Perry on Glee!

Darren Criss and New Directions rock out Katy Perry's latest hit in an all new episode of Fox's hit musical show

Wanna see the Glee kids streaking in the park and skinny dipping in the dark? Hell yes!

Well, we don't have that footage. But we do have an exclusive first look at Blaine (Darren Criss) and the rest of the New Directions singing about all that when they cover "Last Friday Night" on next week's Glee…

This hiatus has been a huge bummer for Glee fans, so a new musical number is just the shot of Gleeky adrenaline we need to get us through the next couple days until "Pot o' Gold" premieres on Tuesday. Remember last time Darren covered Katy Perry? "Teenage Dream" was so magical that rainbows and unicorns had to find new day jobs.

Besides the performance, you should also note in the clip that Santana (Naya Rivera) looks pissed, Finn and Rachel continue to be super cute and everyone else seems to be having a blast. Enjoy the first look below, and be sure to tell us if Blaine's second Katy Perry cover measured up to his last one.

On a related note, Glee celebrated its 300th musical performances yesterday (which we were on set to witness), and Fox released the full 300 songs, including ones that haven't hit the air yet. Check out the list of yet-to-be heard songs below. Some of them are quite interesting, especially "Hot for Teacher." Will Rachel (Lea Michele) serenade Mr. Schuester (Matthew Morrison) again? Doubt it. We're guessing Puck (Mark Salling) sings it for Shelby (Idina Menzel). Ah, speculation gives us such a rush! Now it's your turn.
