This may come as a shock, but Monday, August 17 would have Mark Salling‘s 38th birthday. The actor was only 27 when he starred in Glee, which means it has already been roughly 10 years since the Fox series hit our TV screens! Wow, can you believe how fast time has flown by?

During the show’s run, fans tuned in each week to watch Rachel, Finn, Quinn, Artie, Kurt, Santana, Mercedes, Puck and the rest of the epic glee club sing our absolute favorite songs. The cast covered everything from Journey’s “Don’t Stop Believin'” to Ariana Grande‘s “Break Free,” but no matter what song they performed, they crushed it every single time.

But unfortunately, the epic series (which premiered in 2009) aired its final episode in March 2015, and it was seriously the end of an era. There’s not a day that goes by that we don’t miss it, TBH. But what have the cast been up to since then, you ask? Well, we decided to do some investigating, and it turns out, they’ve accomplished a lot over the last four years. See for yourself! Scroll through the gallery to check out everything the cast of Glee has done since the show ended.
