Tonight the Golden Globe and People's Choice Award winner Glee is coming back to Fox, making its first return to the small screen since December. The series' widespread success has allowed the show to sign on A-list guest stars and perform even more hits. With filming for the spring going full-force, there is a slew of information for the forthcoming season. We've compiled everything you need to know about what you can look forward to.

Though the mega-hit could easily stand on its own, this season we can expect some extreme star power.

Neil Patrick Harris channels Dr. Horrible as his character, Bryan Ryan, works to destroy Will's glee club through his school board influence.  The episode should lead up to some awesome duets between the two rivals; Matthew Morrison told E! that they'll be singing Aerosmith and Billy Joel together. Set to air during May sweeps, this episode is sure to be legendary (according to EW).
