How old is Jeremiah in The Summer I Turned Pretty?

Jeremiah is one of the brothers interested in Belly in The Summer I Turned Pretty. How old is the character, and how old was the actor playing him?

Jeremiah Fisher is one of the main characters in The Summer I Turned Pretty. That goes for both the book series and the TV series. In the Amazon show, he’s portrayed by Gavin Casalegno.

The actor is 22 years old, but he is playing a teenager in the series. Just how old is the character? What’s the age gap like between Jeremiah and Belly? After all, age gaps are often overlooked and romanticized in TV shows when they really shouldn’t be.

Jeremiah’s age in The Summer I Turned Pretty

In the first book/first season of the series, Jeremiah is 16. This is arguably why you see him flirt with everyone—and it is everyone as he is a bisexual character. He makes it clear that he wants to have fun, but that doesn’t stop him from falling hard for Belly as the season goes on.

What is the age gap like between Jeremiah and Belly? Well, it turns out there isn’t one. Belly is also 16 in the first season of the TV series. Lola Tung, who plays the main character, was 19 at the time of filming the first season, so she’s not playing a character that much younger than herself. You can like the two characters together as the age gap won’t give you an icky feeling.

As the seasons (and books) progress, we pick up a summer later on. This means the characters only age by a year in the story. There isn’t that much change between the ages of 16 and 18, is there?

The Summer I Turned Pretty is available to stream on Prime Video.
