Feeling 'Glee'-ful About the Darren Criss Business? Watch the 'Fine' Star in Action!

Have you stopped squealing yet?! Yes, we're all freaking out about the news that Glee cutie Darren Criss will be making his Broadway debut in How to Succeed in Business Without Really Trying after current headliner (and Broadway.com Audience Choice Award winner) Daniel Radcliffe departs. To celebrate Criss coming to the Great White Way, here's a clip from his last New York stage appearance (in June) at Irving Plaza. The hunky star performed many faves with the Warblers, but an especially apt number is this golden oldie. It will indeed be "One Fine Day" when the actor takes the stage at the Al Hirschfeld Theatre on January 3. Clap along with this delightful, happy—dare we say gleeful—video below!
