Including cameos by Kelsey Grammer returns as himself, the return of Will Arnett's Devon Banks, a new romance for Tina Fey's Liz Lemon played by James Marsden, who will appear in several episodes of the half-hour comedy.

Guest stars like Denise Richards playing herself and Bob's Burgers voice star Kristen Schaal are also making appearances on the NBC series.

"Liz is completely re-energized," said Fey. "She does have a new love interest. We don't know how I met him but I have a really handsome boyfriend." Co-star Alec Baldwin, whose character Jack Donaghy is a single dad at the start of the season, offered this observation of Liz's romantic struggles: "One thing that never changes is that Liz is hopeless when it comes to picking men."

Marsden added: "[Liz is] trying to loosen up by dating somebody who is a little more laidback. That could either be good for her or ultimately bad for her." Knowing the hijinks that take place at the headquarters at 30 Rock, it's safe to assume it'll lean more toward the latter.

Of Jack's journey this season, Baldwin teased, "It wouldn't be 30 Rock if we didn't have people doing things that they shouldn't be doing."

NBC's 30 Rock premieres its sixth season on Thursday, Jan. 12 at 8 p.m.
