Colfer and Criss, Behind the Scenes

The duo's rendition of "Baby, It's Cold Outside," in matching jackets with red piping, made holiday music actually bearable last month.

Darren Criss and Chris Colfer, who star in the Golden Globe-winning show Glee, landed the cover of Entertainment Weekly soon after for a cover story this week on the portrayal of gay teens on TV.
