We can't get enough of Elizabeth Banks.

Fortunately, the beautiful, hilarious actress can't get enough of guest-starring on hit sitcoms, either.

More than a year removed from her stint as JD's baby mama on Scrubs, and just a few weeks removed from her appearance on Modern Family, Banks has signed on for a recurring role on 30 Rock in early 2010.

According to Entertainment Weekly's Michael Ausiello, Banks will come aboard the NBC hit as a love interest for Alec Baldwin's Jack Donaghy. She'll appear in at least four episodes.

Her character will actually mark Jack's second high-profile romance of the season: Julianne Moore kicks off a multi-week arc as his high school crush this week. That lucky, dry-witted dog.
