Tina Fey was spotted on the set of 30 Rock yesterday in Manhattan with her costar Alec Baldwin. The actress juggled two phones at once while taping a scene in front of a crowd of extras and onlookers. Tina's NBC comedy will be back on the airwaves to kick off a seventh and final season on Oct. 4. Today, one of the show's producers tweeted a photo of Liz Lemon holding a baby, hinting that maybe Tina's character will become a mom before the comedy comes to a close. Even if there's not a bundle of joy ahead for Liz, there will likely be plenty of surprises to keep things interesting, with past 30 Rock guest stars having included celebrities from Matt Damon to Oprah Winfrey.
