• The "Gossip Girl" reboot airs on HBO Max on July 8.
• Many cast members are close in age to their characters, who are in their junior year of high school.
• Jordan Alexander, who plays queen bee and influencer Julien Calloway, is 27 years old.

Whitney Peak plays Zoya Lott, a new girl at Constance Billard who strikes up a romance with the queen bee's boyfriend. She's a freshman in high school.

In the "Gossip Girl" trailer, Zoya is described as being "not from" the Upper East Side, since she waits for the light while crossing the street. However, she is soon invited into the popular crowd.

Peak is around the same age as her character.

It's common for actors playing high schoolers to be much older than their roles — see "Grease" or the upcoming "Dear Evan Hansen."

However, Peak turned 18 years old on January 28, making her about three years older than her character.

The Ugandan-Canadian actress is most well known for her previous roles on "The Chilling Adventures of Sabrina" and Apple TV's "Home Before Dark."

Evan Mock plays Akeno "Aki" Menzies, who's been dating Audrey Hope for years. He's also 16 or 17.

Mock's character was attached to the word "innocence" in a series promo and can be seen kissing both Audrey and Max Wolfe in the official trailer.

Evan Mock was 24 while filming the first season of the "Gossip Girl" reboot.

Mock is signed to IMG Models and is a surfer and skateboarder. This is his first on-screen role.

Emily Alyn Lind plays Audrey Hope, a popular girl who's dating Aki. She's also 16 or 17.

Despite dating Aki for years, early descriptions of her character said she was "beginning to wonder what more could be out there." She is close friends with Julien Calloway, Luna La, and Monet de Haan.

At 19 years old, she is only a few years older than her character.

Lind's character appears to be an old soul.

"[Audrey is] very into classic, old-fashion type things ... She loves old movies, she loves Betty Davis, she loves Lauren Bacall, she loves Audrey Hepburn, she's very into the finer things in life," Lind told Harper's Bazaar. "She just loves classics. She's not meant to be in this generation, as someone might say. I think that she doesn't use social media as much, she likes reading books."

Jordan Alexander plays Julien Calloway, an influencer who also appears to be the most popular girl at school.

Calloway is featured prominently throughout the reboot trailer. She is an influencer who becomes a target of Gossip Girl, along with her Constance Billard-St. Jude's friend group who "own this school."

Jordan Alexander is the oldest cast member. At 27, she is practically a decade older than her character.

The Canadian actress is also a singer-songwriter. She is most well known for her role in "Sacred Lies: The Singing Bones," though "Gossip Girl" is undoubtedly her biggest acting role to date.

Eli Brown plays Otto "Obie" Bergmann IV, the teenage boyfriend of Julien Calloway.

Obie is described as a "rich do-gooder and German import," who is summed up by the word "privilege." His storyline appears to center around his budding relationship with new girl Zoya. He is likely 16 or 17 years old.

Eli Brown is 21 years old, a few years older than his high school-age character.

The actor is best known for playing Dylan Walker on Freeform's "Pretty Little Liars: The Perfectionists" and for his roles in the films "The F**k-It List" and "Run Hide Fight."

Tavi Gevinson plays Kate Keller, a teacher who wants her privileged students to behave better.

Not much of her is seen in the trailer, but in the first episode we learn she is a teacher at the school. We guess she is in her early 20s. 

Tavi Gevinson is a 25-year-old actress and founder of the now-defunct magazine Rookie.

Her previous acting experience includes roles in "Scream Queens" and CBS' reboot of "The Twilight Zone."

Thomas Doherty plays Max Wolfe, another 16- or 17-year-old student at St. Jude's.

He appears to have a mischievous side and can be seen with Aki in the trailer. The word used to describe his character is "freedom," and he appears to be fluid with his sexuality.

Thomas Doherty is one of the older cast members. He is 26 years old.

The actor previously appeared in the Descendants film franchise, HBO's "Catherine the Great," and Hulu's "High Fidelity."

Zión Moreno plays Luna La, one of Julien Calloway's best friends.

It can be assumed that Luna is also a junior in high school, making her between 16 and 17 years old as well. She is described with the word "style," and she appears to be very into her own appearance.

Zión Moreno is one of the older cast members at 26 years old.

She is most well known for her role as Isabela in the film "Control Z." 

Savannah Smith plays Monet de Haan, one of Julien Calloway's closest friends.

She is one of the "Greek chorus" characters, but she will still have her own fleshed-out storyline, according to Harper's Bazaar. Her character appears to be a social climber and is described with the word "power." She is between 16 and 17 years old, like her classmates.

Savannah Smith is 20. This is her first major acting credit.

Smith is a student at NYU's Tisch School of the Arts and also sings.
