It looks like Jenna Maroney's wedding is in full swing when the final season of "30 Rock" kicks off.
Series executive producer Jack Burditt tweeted the first photo from the first day of shooting. In the photo, Tina Fey is decked out in her finest Liz Lemon plaid and Jane Krakowski is wearing a "bride" t-shirt with the word "slut" scrawled on it. Could this be her bachelorette party?
"30 Rock" kicks off its final season on Thurs., Oct. 4 at 8 p.m. ET.
