NBC's '30 Rock' is at 'The Beginning of The End' with its final season premiere airing on Thursday, October 4. The season's premiere will find Liz Lemon (Tina Fey) reluctantly dealing with being Jenna's (Jane Krakowski) maid of honor and Jack (Alec Baldwin) developing a "shockingly bad fall programming line-up" for NBC, HuffPost TV reported.

NBC revealed that the premiere episode, entitled 'The Beginning of The End,' will also have Kenneth (Jack McBrayer) and Hazel (Kristen Schaal) inviting Tracy (Tracy Morgan) to a dinner party.

The final 13-episode season will host a throng of new guest stars. TV Line reported that Olympic gold medalist Ryan Lochte is scheduled to make a cameo this season, although the details are being kept hush-hush.

Fans will also be able to meet Kenneth's family for the first time. Executive producer and lead star Tina Fey told TV Guide, "We're going to meet Kenneth's [family]... Kenneth's mom will be played by Catherine O'Hara and his mom's 'friend' Ron will be Bryan Cranston." Details surrounding the when and why the two characters is being kept under wraps but TV Guide reported it may have something to do with Kenneth and Hazel's "non-sexual boyfriend-girlfriend thing."

Another familiar face will be returning for the show's final season. TV Line reported that actor Maulik Pancholy will return as Jack's assistant Jonathan during the season premiere. Pancholy was a series regular during Whitney Cumming's comedy 'Whitney' last year and will not be returning to the show after his character came out as gay.

'30 Rock' returns for its final season on October 4 at 8 p.m. ET on NBC. It is scheduled to run 13 final episodes ending in January.
