'30 Rock' fans have been early awaiting for the new season, which was delayed until January due to Tina Fey's pregnancy.

Now, the first teaser is here. Wondering what Liz Lemon, Jack and all the rest have been up to? So have we. 

Besides the usual hijinks from Tracy and Jenna and Kenneth, we get a glimpse of guest star Kelsey Grammer as well as something about a big, shocking secret that Liz has been keeping from everyone.

'30 Rock' returns for its sixth season on January 12 at its new time of 8PM. Let's hope they can find a way to poke some fun at Alec Baldwin and his airplane adventures. Watch the funny promo below.
