He tells Billboard.com, "We're working on it - we're really excited and it's something I've been wanting to do for a long time. I'm so thrilled that it's something that can happen because of Glee... I hope I can do it justice and make it something that people can really enjoy."

Darren Criss and Matthew Morrison aren't the only Glee stars to put out their own solo songs - Mark Salling, who plays bad boy Puck, has recorded two studio albums.
