The Glee stars were spotted joking around at Club XS in Toronto, Canada after the awards show. Sporting a large afro wig, Overstreet, 23, and fellow castmate Criss, 25, mingled with celebs and took photos with fans.
Jokes aside, the boys were actually there to help out a notable cause.
The event was a fundraiser for MusicCounts, which helps children in Canada get access to music programs through their schools.
As actors who play students in a glee club, Overstreet and Criss know a thing or two about music in schools.
