Lea Michele (Rachel) already gave us a bit of inside scoop on what to expect from Glee’s upcoming Regionals episode, now Grant Gustin (Sebastian) is taking a turn! Grant returned to the Glee set to film Season 3, Episode 14: “On My Way” on February 7.

Take a look at what he was up to.

Bright and early on Tuesday morning — at 6:23 AM, to be exact — Grant tweeted, “Clean shaven and ready to be a teenager all day long. #early” What, no scruff for Sebastian? Sad...

Later in the day, Kevin McHale (Artietweeted this photo of he and Grant on set. Too bad these guys can’t be better friends on the actual show. Not with all the mischief Sebastian has plannned for Regionals!

Grant didn’t finish filming until late in the evening. At almost 9 PM, he tweeted,“After a long day of dancing in new shoes, day 1 of regionals is done! Time to sleep and get ready for day 2!! #goodtimes

We know that the New Directions will be rapping in one of their three songs, but other details about the music are still being kept under wraps. Rumours around Tumblr say the Warblers will perform Lenny Kravitz’s “Stand.”

What, no Michael Jackson? Didn’t we just go through a huge face-off over the rights to perform a Michael tune? Hmm, hopefully this means that the Warblers will get to perform more than one song, too! (On second thought, there’s probably not enough time. Not that we’re still bitter or anything...)
