"Hey get an Instagram, would ya!" Hilary Duff shouts at her Younger co-star/director, Miriam Shor, who plays marketing executive Diana Trout, but the directive also could be extended to Peter Hermann aka publisher Charles Brooks, as well as Jennifer Westfeldt, Charles' ex-wife and author Pauline Turner-Brooks.

Luckily, the other popular actors who bring the show's much-loved characters to life choose to share parts of their lives on social media. While some actors are still building a following, others, with a long list of credits beyond their current show, have amassed quite a number of devotees.

Chris Tardio - 3,076 Followers

Chris Tardio's portrayal of Enzo softened the heart of the jaded Diana and won over fans with his Italian good looks and ability to look as good in a t-shirt, jeans and toolbelt as he does in a tux.

Active since 2000, with his first credit being a recurring role on The Sopranos, he's spent his career, so far, in television. As one can see from his IG, Tardio's also an artist, photographer, chef, and world traveler. Being on such a popular show and with several post-Younger projects in production will surely increase his fan base even more.

Tessa Albertson - 4,507 Followers

Tessa Albertson, Liza's college coed daughter, Caitlin Miller, is a bit different than her alter ego. The most they seem to have in common is their impressive educations: Albertson went to Princeton and her character attends Vassar.

She's been acting in movies and on TV since 2008, and her IG shows not only a flair for the dramatic but quite a sense of humor. If she keeps getting roles in projects with the same caliber as Younger, and works with actors as talented, her following is bound to one day rival that of her more seasoned co-stars.

Michael Urie - 85.8K Followers

The boyishly handsome Michael Urie, who plays the self-possessed book agent Redmond, has been a working actor since 2002. His breakout role as editorial assistant Marc St. James on Ugly Betty is where he, no doubt, began to develop his impressive following.

Urie's IG attracts so many fans, obviously because he offers a mix of professional (stage and screen) as well as personal pictures (especially of his dog-daughter, President McKinley), plus shows a true devotion to activism in the LGBTQ+ community by attending marches and events, as well as performing in plays that support related causes.

Molly Kate Bernard - 125K Followers

Molly Kate Bernard may play Kelsey's sidekick, but the actor steals every scene she's in. Like her character, publicist Lauren Heller, Bernard has sparkle to spare.

Fans of hers from Chicago Med and Transparent are clearly drawn to the actress' Instagram, who shares her life with wife Hannah and their dog, playful pictures that show off her big personality, artsy shots, plus behind-the-scenes photos with castmates and info about her upcoming film, Milkwater. She also shows her support for social justice issues.

Laura Benanti - 149K Followers

Laura Benanti (Quinn Tyler) is a Tony-award-winning Broadway actress who draws her fan base from theater and moviegoers, as well as TV watchers.

Famous for her Melania Trump impersonation on The Late Show with Stephen Colbert, as well as Detective Amaro's wife on Law & Order: SVU, as well as many other shows, including the upcoming Gossip Girl reboot, Benanti's IG focuses mostly on family and support for racial justice, with a smattering of professional shots from shows she's been on and upcoming projects.

Debi Mazar - 505K Followers

Debi Mazar (Maggie) may not have the most IG followers, but she has the most interesting of Insta pages. As a makeup artist entrenched in the NYC downtown scene of the 1980s, Mazar was friends with everybody destined to be anybody.

This included Spike Lee, Marc Jacobs, and drummer-turned-singer Madonna, whose videos Mazar would appear in before becoming an actress in her own right, starring in a seemingly never-ending list of films such as Goodfellas and Malcolm X, and TV shows like Entourage. Aside from her wild youth, fans of her IG are treated to Mazar's favorite things: family, food, and Italy.

Sutton Foster - 620K Followers

Sutton Foster (Liza Miller), like Laura Benanti, has a fan base from her extensive -- and Tony-winning -- work on Broadway, as well as those who've followed her career doing episodic television for the past decade and a half. She is also the author of the upcoming "Hooked: How Crafting Saved My Life," out in October 2021.

The star of Younger has an IG to satisfy her thousands of followers because it offers a look at the wholesome actress's family and career. There's everything from her love of crocheting (she made a purse) to her husband and child to her castmates and the singer/dancer in costume for her many stage roles, such as Thoroughly Modern Millie.

Nico Tortorella 686K Followers

Nico Tortorella, who plays the tattooed Josh, started out as a Ford Model, which explains why his IG is basically all pictures of himself, either selfies or taken professionally. He seems to be giving his thousands of followers what they want: lots of Nico/Josh eye candy.

He's more than just a pretty face though. Acting since 2009, Younger is the most recent in a long line of TV shows he's been in, including The Beautiful Life: TBL, Make It or Break It, The Following, and The Walking Dead: World Beyond.  He too is a published author to two books: "All Of It Is You: Poetry" and "Space Between: Explorations of Love, Sex, and Fluidity."

Charles Michael Davis - 839K Followers

Charles Michael Davis (editor Zane Anders) is an actor, director, model and photographer. His IG is all about how he takes black-and-white photography to the next level, with very little postings about his personal or professional life.

It's probably safe to say, Davis' IG following is due to this handsome and talented actor's presence on TV since 2005, where, besides on Younger, he's made his mark with roles on Switched at Birth, The Game, Grey's Anatomy, The Originals, Chicago P.D., For The People, and NCIS: New Orleans.

Hilary Duff - 17.1M Followers

You are reading that number correctly. A small country could be populated by the followers of Hilary Duff (Kelsey Peters). She was born in 1987 and her resume starts in 1997, with her claim to fame role of Lizzie McGuire coming along only a few short years later, meaning her fans were kids like her and they grew with her from child star to teen star and now as an adult actress. Her fans love her whether it be in films or on TV. After Younger, she'll be starring in the new How I Met Your Father.

Because her fans are so loyal and ardent, Duff gives back with an IG that offers glimpses into her full personal life as a wife and mother. She's also the author of three novels and a children's book.
