An NBC rep tells Zap2it the “30 Rock” pickup is for 13 episodes and that 2012-13 will be the show’s last season. That confirms a couple weeks of speculation that the show’s last season would be a short one.

Ratings for “30 Rock” have never been stellar, but the Emmy-winning series fell on harder-than-usual times this season. It’s averaging about 4.6 million viewers and a 2.1 rating among adults 18-49. Star Alec Baldwin has also frequently made noise about leaving the show in the past couple months; he’s under contract through next season, but he’ll be getting his wish.

“Do No Harm,” NBC’s third drama pickup of the spring after “Revolution” and “Chicago Fire,” is a spin on “Dr. Jekyll and Mr. Hyde.” Steven Pasquale (“Rescue Me,” “Up All Night”) stars as a talented neurosurgeon whose alter ego threatens to wreck his life and career. Alana de la Garza (“Law & Order”) and Phylicia Rashad (“The Cosby Show”) also star; David Schulner (“The Event,” “Kings”) created the show.

UPDATE: Pretty much as soon as we hit “publish,” word came down that NBC has picked up yet another new show:

“Infamous” (formerly “Notorious”) stars Meagan Good as a detective who goes undercover to solve the murder of a well-known heiress. Good’s character knows the players well — she grew up around the victim’s family because her mother was their housekeeper. Liz Heldens (“Friday Night Lights,” “Mercy”) is the creator.

That makes an even 10 shows NBC has ordered for next season.
