How old the stars of 'The Sex Lives of College Girls' are compared to their characters' ages

• HBO Max's "The Sex Lives of College Girls" was created by Mindy Kaling and Justin Noble.

• It centers on four characters played by Pauline Chalamet, Amrit Kaur, Reneé Rapp, and Alyah Chanelle Scott.

• Here's how old the cast members are compared to the college characters that they play on the show.

Pauline Chalamet stars as 18-year-old Kimberly Finkle, a freshman at New England's Essex College.

Kimberly is from Gilbert, Arizona, which she refers to as the "whitest town in the world." She's the most sheltered of the four main characters since she didn't go out much, try drugs, or drink alcohol prior to going to college.

Her age isn't explicitly stated, but she's likely 18.

In order to afford to attend Essex, Kimberly gets a job at Sips, the campus coffee shop.

Chalamet is 30 years old in real life.

The actor, who's the older sister of Timothée Chalamet, had small roles on shows like "One Life to Live" and "Royal Pains" before making her feature-film debut in "The King of Staten Island" (2020) starring Pete Davidson.

Chalamet has also written and directed shorts like "Between Fear and Laughter" and "Cosmic Disaster."

Amrit Kaur plays Bela Malhotra, an 18-year-old aspiring comedian and sex-positive freshman at Essex.

Bela idolizes comedians like Seth Meyers, who was previously a writer and performer on NBC's "Saturday Night Live" before landing his own late-night talk show.

She chose to attend Essex specifically because of The Catullan, the college comedy magazine that's a big deal in the comedy world since a lot of "SNL" writers got their start through the publication.

Bela gets accepted into The Catullan but leaves after experiencing sexism and being sexually assaulted by the coeditor, Ryan (Conor Donnally).

By the end of season one, two other women, Evangeline (Sierra Katow) and Jo (Cheyenne Perez), quit the magazine and tell Bela they want to launch a ladies-only comedy publication.

At 29 years old, Kaur is several years older than her "SLOCG" character.

Kaur, who's from Ontario, Canada, had some difficulty with the audition process for "SLOCG" because she didn't have an  O-1 visa (a nonimmigrant visa for an individual with extraordinary ability or achievement).

"When the audition came out, they said they only wanted to audition people with an O-1 visa," Kaur told Refinery29. "I didn't have it, but my heart connected to the part and my rep and I were just like: Fuck it, let's go for it. If they like me they'll have to figure it out."

Kaur said she auditioned and got a callback for a chemistry read, but it got canceled because they found out the actor didn't have a visa.

Kaur said that she didn't get the O-1 visa on the first try, but for the second attempt, Kaling, Noble, and the producers wrote letters to "convince the government that I should have this part and no one else could do it."

Reneé Rapp portrays Leighton Murray, 18, a popular and rich freshman who grew up in New York City's Upper East Side.

She's initially closed-off and aloof but becomes a loyal friend to her suitemates as the show progresses.

Leighton starts college closeted because she doesn't like the concept of coming out and having her sexuality define her. In the season one finale, during a heartfelt scene, she reveals to Kimberly that she's gay.

At 22 years old, Rapp is closest in age to her character.

Rapp is known for playing Regina George in the Broadway musical "Mean Girls."

She juggles acting with singing and released her debut EP, "Everything to Everyone," on November 11.

Alyah Chanelle Scott stars as 18-year-old Whitney Chase, a soccer star and daughter of a senator.

Her season one arc centered on her secret relationship with her soccer coach, Dalton.

Whitney eventually told Coach Wood, her mom, and her friends about the affair.

Scott is 25 years old in real life.

The actress, who's from Texas, previously starred as Nabulungi in the US national tour for the musical "The Book of Mormon."
