No, we don't mean knocking up cheerleaders on Glee or anything like that.
Cory is making a musical effort off-camera. On Sunday, he did his very first performance with his band, Bonnie Dune, at the Roxy Theatre in L.A., where a bunch of his costars were there to support.
So who was and wasn't in the house?
"They were all incredibly nice and gracious," a source says of the stars.
But where was Cory's onscreen love interest, Lea Michele?
She had plans of her own that night with another Glee guy. Lea was spotted leaving the Pantages Theatre arm-in-arm with Chris Colfer after they saw the musical Hair.
Can't wait to see the whole cast hit the carpet together at the Golden Globes this weekend!
