'Glee' Preview: Hear Blaine and Artie Sing 'Last Friday Night'

"Glee" isn't back until November 1st, so you'll have to wait a while before you find out what happens next with Kurt vs. Brittany, Mike vs. his dad, and Rachel vs. pretty much everyone. Blame it on baseball.

But "Glee" has still released a couple of previews of the upcoming songs for the episode, one of them being--surprise, surprise--another Katy Perry song. I haven't been counting, but it seems that just as Katy Perry is aiming for the record for #1 singles, "Glee" is aiming for a record of Katy Perry covers.

Here's the twist with this one: the cover is of Katy Perry's "Last Friday Night (T.G.I.F.), and it's sung by Blaine (Darren Criss) and Artie (Kevin McHale). Both Criss and McHale appeared in Perry's music video for this song, so there's a little nod to Perry fans there. Not only that, but there was this video that had Criss and other "Glee" regulars lip-synching to the song.

The inclusion of Katy Perry in the next episode marks a return to pop for the show, which has mostly stuck to showtunes so far this season.
