Darren Criss CAUGHT Shirtless at the Coachella Festival!

A shirtless Darren Criss was spotted decorated in some face paint at this weekend's Coachella festival.

Criss has some reasons to be celebrating. He's on the cover of Billboard this week. He tells the magazine he's planning a solo album:

"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," and like the Warblers album I hope I can do it justice and make it something that people can really enjoy."
