After a break to accommodate the World Series, Glee is returning with all new episodes beginning November 9, including the arrival of much-buzzed-about new cast member Darren Criss. The actor, who was recently voted Glee's most anticipated newcomer by Broadway.com readers, will head up a rival school singing group, the Dalton Academy Warblers. Rumor has it Criss' character Blaine may be a love interest for Kurt (Chris Colfer). Whether it's true or not, Criss will surely get viewers' hearts racing thanks to this new clip of the rising star performing the Katy Perry smash "Teenage Dream." Slip into some skin-tight jeans and watch Criss' performance below.
