Lemon out! Judah Friedlander celebrated the filming of the final episode of “30 Rock” Wednesday by giving everyone a personalized trucker hat. “Everyone on the crew and everyone in the cast got a hat,” Katrina Bowden tells Page Six. “Mine said ‘Italian Senator’ on it because there was a Halloween episode and I was wearing a bikini that said ‘Italian Senator’ . . . Jane [Krakowski]’s hat said ‘Cam-er-a’ on it and Tina [Fey]’s said ‘Cupcake Sandwich,’ which is a reference to a recent episode.” Bowden added, “[Judah] has so many hats . . . he has garbage bags full of letters.” The cast celebrated the end of the show with a Nokia Lumia 920-sponsored party Thursday at Capitale, where guests were able to take photos inside a re-creation of Alec Baldwin’s character Jack Donaghy’s office and add stickers of the show’s more notable quotes. “It was a good time for us to celebrate instead of cry,” Bowden told us. Lorne Michaels, Jack McBrayer, Scott Adsit and the rest of the cast were also there.
