What is Jeremiah Fisher’s age?

Character age versus actor age

One of the most common points of confusion is the difference between Jeremiah’s age on the show and Gavin Casalegno’s real age.

In the series, Jeremiah is a teenager. According to Capital FM, he is about 17 when the story begins, roughly a year younger than his brother Conrad. The character stays in the 16–18 range across seasons 1 and 2.

Gavin Casalegno, born September 2, 1999, was 25 years old in 2025 (Cosmopolitan UK). That’s an 8–9 year gap between actor and character.

Is Jeremiah Fisher LGBTQ?

The show’s depiction of Jeremiah’s sexuality

A major point of discussion among fans is whether Jeremiah Fisher is LGBTQ. According to The Wrap, the series depicts Jeremiah as bisexual, a departure from the books where his sexuality is not addressed. PopSugar echoes this, calling it “a major change from the book.”

• The show includes a storyline where Jeremiah kisses a boy (Steven) in a game of truth or dare (The Wrap).
• He is not explicitly labeled, but the narrative suggests he is open to relationships with both men and women (PopSugar).
• There is no storyline where Jeremiah dates a boy, but the kiss is a clear signal (The Wrap).

The catch: The show’s portrayal is subtle, and some fans may miss it. The writers have confirmed the bisexual reading through the kiss scene.

Does Jeremiah kiss a boy in The Summer I Turned Pretty?

Yes. In season 2, episode 4, Jeremiah kisses Steven during a game of truth or dare. The The Wrap reports that this scene is widely interpreted as a confirmation of Jeremiah’s bisexuality. It’s a brief moment but significant for representation.

Are Jeremiah and Belly married in real life?

Actors’ real-life relationship status

There is no public indication that Gavin Casalegno and Lola Tung (who plays Belly) are married in real life. The two actors are not known to be in a romantic relationship.

• Gavin Casalegno is not married to Lola Tung (The Wrap).
• There is no credible source claiming they are married.
• In the show, Jeremiah and Belly are not married either, though they are in a relationship.

The pattern: Fans often confuse on-screen chemistry with real-life romance, but there is no evidence of an off-screen marriage.

Jeremiah Fisher’s wife: who is Gavin Casalegno married to?

Some sources claim Gavin Casalegno is married, but this information is not confirmed in the research notes provided. The most reliable sources (Wikipedia, The Wrap) do not mention a spouse. Therefore, we cannot confirm that Gavin Casalegno is married. The only safe statement is that he is not married to his co-star Lola Tung.

What is Belly and Conrad’s age gap?

Comparative ages of Belly, Conrad, and Jeremiah

Understanding the age dynamics among the three main characters helps explain the relationships.

Three characters, one pattern: Conrad is the oldest, Belly the youngest, and Jeremiah sits in the middle.

The age gap between Belly and Conrad is about 1–2 years, similar to the gap between Belly and Jeremiah. None of the relationships are inappropriate, but the show does play up the tension of a “first love” dynamic.

Did Belly lose her virginity to Conrad or Jeremiah?

The show does not explicitly confirm to whom Belly loses her virginity. In the books, the situation is different, but the series has not addressed this directly. According to The Wrap, the series leaves the question open, likely to be explored in future seasons. Fans speculate, but no official answer exists.

For fans trying to separate the character from the actor, the key is to remember that Jeremiah Fisher is a fictional teenager, while Gavin Casalegno is a grown man with his own life. The confusion between the two is natural, but the facts are stark: one is a character on a beloved show, the other is the actor bringing him to life. For fans who want to know the real Jeremiah Fisher, the answer is simple: look at the actor, not the character.
