Sneak Peek of 'Teenage Dream' On 'Glee' (MUSIC)
Glee took a hitaus this week, but next Tuesday they're back and better than ever!
Newbie (and rumored love interest for Chris Colfer's Kurt) Darren Criss will be making his long awaited debut and belts out one of summer's hottest hits "Teenage Dream."
Also, we're happy to announce that mash-ups are making a comeback! The guys take on "Stop in the Name of Love" and "Free Your Mind" while the ladies do "Living on a Prayer" and "Start Me Up."
