Her co-stars Kyra Sedgwick, Sam Rockwell and Nia Vardalos were also unaware of her cameo as she made her entrance just in time. “She's known about the show for weeks, but whether or not she could perform depended on her shooting schedule. She actually came right from the set," a source said of Aniston.
“She did fantastic, and the crowd went wild. What's not to love? It's Jennifer Aniston," said Aniston's good friend Kathy Najimy.
