Now she just has to make sure no one finds out the secret only she and her best friend Maggie share.

Hilary Duff Initially Declined: Hilary Duff initially turned down the role of Kelsey because the show was filming in New York, where she didn't live. However, Darren Star, the creator, personally called her and insisted she take the role, stating he wouldn't accept "no" for an answer.
Sutton Foster's Musical Background: Despite Sutton Foster's extensive Broadway background, she requested that there be no musical scenes for her character, Liza. She felt that Liza wouldn't be able to hold a tune.
Real-Life Inspiration for Fictional Works: The show cleverly incorporates real-world literary references, including allusions to authors like Karl Ove Knausgård and Candace Bushnell, even creating fictional authors inspired by them. Annabelle Bancroft, an author in the show, is based on Candace Bushnell, the author of Sex and the City.
A Novel Within the Show Got Published: In season four, Pauline, Charles's ex-wife, writes a novel called Marriage Vacation, which gets published within the show. Interestingly, this fictional novel was actually published in real life, containing Easter eggs related to Younger.
Origin of Liza's Name: The series creator, Darren Star, revealed that he named the lead character "Liza" because he wanted to incorporate the word "lies" into the narrative. This connection wasn't explicitly mentioned in the script until season four.
