After joining Glee with a rousing performance of Katy Perry’s “Teenage Dream” during the second season, Darren Criss instantly became one of the hit show’s most recognizable cast members.

Criss spoke about fending off moms and teen girls on the Glee tour, his upcoming turn opposite Kristen Wiig in the raunchy adult comedy Imogene, and why his parents grounded him before his prom.
