PASADENA, Calif. - Don’t forget to tune into the new hit reality-competition series America’s Kidz Got Singing.

Okay, to see America’s Kidz Got Singing, you actually have to tune into the sixth-season debut of 30 Rock, which airs Thursday, Jan. 12 on NBC and Citytv.

As everyone returns from holiday break, Jenna (Jane Krakowski) has become the judge everyone loves to hate on America’s Kidz Got Singing. But Jenna’s Simon Cowell-esque success leads Jack (Alec Baldwin) to start to question the show’s family value.

Besides Jenna, the other judges on America’s Kidz Got Singing are John McEnroe, playing himself, and D’Fwan, played by Tituss Burgess. Meanwhile, Tracy (Tracy Morgan) becomes chagrined when his usual antics fail to aggravate Liz (Tina Fey), and Kenneth (Jack McBrayer) prepares for the end of the world.

There also are a couple of new network shows debuting on Thursday: The sitcom Rob, with Rob Schneider, is on CBS; while Bones spinoff The Finder is on Fox and Global.
