There is little detail about Tyra's role but it was reported that Serena will get a job as a publicist taking charge of Ursula's movie premiere night. No episode date was suggested.
Apart from sharing some scenes with Blake Lively, Tyra will also meet another guest star Hilary Duff who plays a movie star in disguise, Olivia. They have shot their joint scene and Duff said, "It was fun to work with her in a different atmosphere than appearing on her show. She looked beautiful and did a really great job. She had the flat hair that squiggles on her forehead. Very flapper-ish!"
