Hilary Duff and cast of 'Younger' on baring it all onscreen

The cast of "Younger" visited BUILD Series NYC to chat about the newest season of the hit TV show.

"Younger" features the adventures of single mom Liza (Sutton Foster) whose friend Maggie (Debi Mazar) encourages her to pose as a twentysomething instead of re-entering the workforce. Liza lands an assistant job for "Devil Wears Prada"-esque Diana (Miriam Shor) and teams up with coworker Kelsey (Hilary Duff). Liza finds herself caught in a love triangle between young tattoo artist Josh (Nico Tortorella) and distinguished Charles (Peter Hermann). Molly Bernard adds a flair of eccentricity as Liza and Kelsey's pal Lauren.

Actors Sutton Foster, Hilary Duff, Debi Mazar, Miriam Shor, Molly Bernard, Nico Tortorella, and Peter Hermann discussed how the season three finale bombshell would affect the fourth season, how they keep up with their characters' slang, and surprising fan reactions to the show.

The cast reflected on how their characters have grown since the show's beginning.

"You broke [Liza] open," Foster said to Mazar, "Yes, [Liza] is a mess, but [her] life is more authentic now than it ever was before."

"You're welcome," quipped Mazar.

The panel also delved into how the show created by Darren Star ("Sex and the City," "90210") pushes the boundaries of what typically is shown on TV Land.

"We get naked a lot," said Mazar.

"I had to have my boob out this year!" exclaimed Duff. "I gotta tell my mom, 'No, don't watch that one, I'm sorry.'"

The cast then described their hopes for their characters' storylines.

Duff on her "beautiful mess" of a character Kelsey, "I hope [she has] more success in the business place...Women deserve it. We deserve to be sitting in that seat."

"I hope I still get to be really sexually active," Mazar said. "My character is a little bit slutty, and I like that because [I've been] married a long time and I get to live out my fantasies at work."

Watch "Younger" on TV Land on Wednesdays at 10 p.m. EST or on Hulu!
