Alec Baldwin has cleared the air on his future with 30 Rock, days after hinting on Twitter at a possible exit before the show's inevitable end.

On Monday, during a lobbying session for Americans for the Arts in Washington, D.C., the 54-year-old actor confirmed with the Associated Press that he is staying on the NBC series until the show's seventh (and possibly last) season (via the Huffington Post).

Baldwin, who plays the Lorne Michaels-inspired Jack Donaghy on the show, also suggested that NBC is in dire need of a line-up change, as ratings have not been favorable this TV season. Last week, both 30 Rock and Community hit a series low in ratings, with only 2.8 million and 3.1 million tuning in, respectively, Entertainment Weekly reported.

In April 2011, 30 Rock was raking in some 4.4 million viewers, according to TV By The Numbers.

On Apr. 11, Baldwin put 30 Rock fans at the edge of their seats when he wrote on Twitter, I think I'm leaving NBC just in time.

His comment came at the end of a long Twitter rant that addressed everything from his Canadian stalker and a stalker of another kind: the media.

Outside my apt today, along side the other stalkers from the tabloid press, a crew that identified themselves as being with the Today Show . . . the television crew camped outside my apt said they were with the Today Show. #howthemightyhavefallen, Baldwin wrote last week.

I haven't appeared on the Today Show in many years. But did they have to camp outside my apt? A story about stalking sure brings out the stalkers in the media. But, the Today show? he continued.

The next day, Baldwin added even more fire to the 30 Rock rumor mill, again, via Twitter.

As far as I know, 30 Rock is back next year. But all things must pass. New shows. New people . . . but aren't you infinitely curious about the kinds of things Tina will do when the show is over? I know I am. I think Tina will write, produce, act in and direct some great films . . . people need new things, creatively, he wrote in a series of tweets.

Just over one week ago, Canadian actress Genevieve Sabourin was arrested outside Baldwin's Manhattan apartment on charges of stalking and harassing.

Sabourin was released without bail the next day by Manhattan Criminal Court, and ordered to temporarily stay away from Baldwin (and new fiancé Hilaria Thomas).

A new episode of 30 Rock will air this Thursday on NBC.
