Jeremiah Summer I Turned Pretty: Age, Sexuality Facts

If you’ve watched The Summer I Turned Pretty, you know Jeremiah Fisher isn’t just the golden boy with a grin — he’s a character whose personal story has sparked real conversations. From his sexuality to his place in the love triangle, here’s what the facts actually say, backed by the show, the books, and the people who made them.

Character: Jeremiah Fisher · Portrayed by: Gavin Casalegno · Age in Season 2: 17–18 · Sexuality: Bisexual (confirmed by Bi.org) · Sibling: Conrad Fisher (older brother) · Actor birth year: 1999

Seven key facts about Jeremiah Fisher — one pattern: the show expands his story well beyond the books, particularly around sexuality and relationships.

Is Jeremiah LGBTQ?

Yes — and the show is explicit about it. The Prime Video series presents Jeremiah Fisher as bisexual, a departure from the books where his sexuality is not explored. Capital FM reports that the character is described as having relationships with both girls and guys. The Bisexual Resource Center (Bi.org) lists Jeremiah as a canonically bisexual character, giving fans a clear answer.

Did Jeremiah date a boy?

• He dated a boy named Blake, introduced in Season 3, Episode 7 (Betches).
• Earlier, in Season 1, Episode 3, Jeremiah is shown kissing another guy at a party (The Direct).
• Author Jenny Han has described Jeremiah as “sexually fluid” and “a young person who’s figuring out where he falls” (Capital FM).

The implication: the show intentionally broadens Jeremiah’s identity beyond the books, making him a more complex and representative figure for the audience.

What is Jeremiah’s real age?

In the series, Jeremiah is about 17 when the story begins, according to Capital FM. By Season 2 he is 17–18. In the books, he is around 25 by the end of the trilogy (Capital FM).

What is Belly and Jeremiah’s age gap?

• Belly is 16 in Season 1, making the gap about one year.
• The exact age gap is not explicitly stated in the show, but the one-year difference is consistent with the book timeline.

What this means: the age difference is small enough that it doesn’t create a power imbalance, keeping the focus on emotional dynamics rather than age-gap issues.

Who is Jeremiah’s ex, Blake?

Blake is Jeremiah’s ex-boyfriend, introduced in Season 3, Episode 7 of the Prime Video series. The character is mentioned but does not appear on screen (Betches). This relationship is a key part of Jeremiah’s bisexual storyline, confirming that his past includes a serious romantic connection with a boy. The books did not explore this aspect of his life (The Direct).

The catch: because Blake is only referenced off-screen, some viewers feel the show could have done more to show rather than tell. Still, the mention serves as a concrete confirmation of his sexuality.

Is Jeremiah Conrad’s brother?

Yes. Jeremiah is the younger brother of Conrad Fisher. They are the sons of Susannah and Adam Fisher (Capital FM). Their relationship is central to the story — both compete for Belly’s affection, but their bond as brothers is tested and complicated by the love triangle.

Why this matters: the sibling rivalry isn’t just drama; it forces both characters to grow. Jeremiah’s loyalty to Conrad often conflicts with his feelings for Belly, making him one of the more morally nuanced characters in the series.

Did Belly lose her virginity to Conrad or Jeremiah?

In the book series, Belly loses her virginity to Conrad (The Summer I Turned Pretty Wiki). The show has not explicitly depicted this event, leaving it a point of debate among fans. The series may handle it differently, as the adaptation has already made significant changes to character arcs.

The trade-off: book readers have a clear answer, but show-only viewers are left guessing. The ambiguity keeps the love triangle alive, but it also means the showrunners have room to reimagine this pivotal moment.

Does Gavin Casalegno have any children?

As of 2025, Gavin Casalegno does not have children (Capital FM). He is married, but the race of his wife is not publicly known — no official confirmation has been released. There is also no public evidence that Lola Tung (Belly) attended his wedding.

What race is Gavin Casalegno’s wife?

Not publicly disclosed. The actor keeps his personal life relatively private, and no reliable source has confirmed her ethnicity.

Did Lola Tung go to Gavin’s wedding?

No public evidence supports this. While the cast is close, attendance at private events is not typically documented unless shared on social media — and no such posts exist.

What this means: the actor’s private life is just that — private. Fans should be careful not to assume details from social media speculation.

Book vs. Show: How Jeremiah Differs

One pattern, four key differences: the show expands Jeremiah’s story in ways that matter for representation and character depth.

The takeaway: the show uses the character to reflect a more inclusive vision, while the books stick to a more traditional arc. Neither is wrong, but the difference is deliberate.

For anyone who’s still wondering whether Jeremiah is LGBTQ+, the answer is a confident yes — backed by the people who created him.
