Have there really been 600 Glee songs already? We need a lozenge just thinking about all the singing that's been required to make this milestone happen. And we're not the only ones who are thrilled about Glee's upcoming 600th musical number, as Lea Michele (Rachel) is ecstatic, too!

The show's 600th tune will air next spring during Season 5, Episode 9: "Frenemies." And who will get the honor of singing the momentous song? That belongs to Artie (Kevin McHale) and Tina (Jenna Ushkowitz), the former couple that surprisingly has not yet had a duet together. Get excited!

To properly fete the occasion, Glee's cast and crew had a little party on the set, complete with champagne! On November 19, Lea tweeted about the moment:



Awww! It's adorable to see how excited Lea is to reach this milestone, not to mention that she points out how much she still loves her job. We could see some people getting jaded after 200 or 300 songs, let alone a whopping 600, but Lea is clearly not one of those people.

In addition, Kevin McHale posted a photo to Instagram of himself lifting a glass with fellow Glee stars Darren Criss (Blaine) and Jacob Artist (Jake), along with the show's co-creator Brad Falchuk.

"#glee600thnumber celebration! @darrencriss @jacobartist & Brad," Kevin captions the pic. 

You know it's a party when Darren has loosened his bow tie. And what is that on Jacob's cheek? Perhaps it's a sticker for the occasion? Suddenly, we really want one of those stickers.

Okay, so we're not happy to have wait until spring to see this big musical number. Still, it's great to see how much fun the Glee cast is still having after all those years — and all those songs. Bottoms up!
