STAGE TUBE: Sneak Peek - Jenna Judges a Talent Competition on Tonight's 30 ROCK on NBC

NBC's 30 ROCK returns tonight with all new episodes. On tonight's episode, entitled 'Dance Like Nobody's Watching', everyone returns from holiday break to find that NBC's new talent competition, "America's Kidz Got Singing", is a hit. But Jenna's role as the judge everyone loves to hate causes Jack to question the show's family value. Much to his chagrin, Tracy's usual antics fail to aggravate Liz (Tina Fey), while Kenneth (Jack McBrayer) takes the day off to do his dream chores as he awaits the Rapture.

Multiple award-winning comedy 30 ROCK is told through the comedic voice of Emmy and two-time Golden Globe winner Tina Fey as variety show producer Liz Lemon. The series also features two-time Emmy and three-time Golden Globe winner Alec Baldwin as top network executive Jack Donaghy and Emmy nominee Tracy Morgan as Tracy Jordan, the unpredictable star of Lemon's hit variety show, "TGS with Tracy Jordan." Lemon constantly has her hands full, juggling corporate interference from Donaghy and off-the-handle star antics from Jordan, all while attempting to salvage her own personal life.

Also rounding out the cast are three-time Emmy nominee Jane Krakowski as Jenna Maroney, the co-star of "TGS"; Scott Adsit as the variety show's producer Pete Hornberger; Emmy nominee Jack McBrayer as Kenneth, the over-eager and effortlessly endearing NBC page; Judah Friedlander as Frank, the sardonic slacker on the writing staff; and Keith Powell as Toofer, the sophisticated yet sarcastic, Harvard-alum writer.

30 ROCK airs Thursdays at 8:00 pm/et on the NBC network.
