Twelve diverse unknowns -- including 4-foot-9 Matheus and plus-size Hannah -- vie for a stint on the musical smash Glee in this charming reality competition. Stars from the Fox series (Darren Criss!) help with challenges, such as starring in a yearbook-themed video for Katy Perry's "Firework." Each week's bottom three get to sing a last-chance song for the judges. Oh, the drama! (Oxygen, 9 P.M.)
