Eight key facts, one pattern: the difference between the fictional Jeremiah and the real Gavin Casalegno creates a lot of fan curiosity. Here’s a quick reference table.
| Attribute | Value |
|---|---|
| Character Name | Jeremiah Fisher |
| Actor | Gavin Casalegno |
| Born | September 2, 1999 |
| Age (2025) | 25 |
| Height | 6 ft 0 in (approx) |
| Marital Status | Married to Cheyanne Casalegno |
| First Appearance | The Summer I Turned Pretty Season 1 (2022) |
| Known For | Playing Jeremiah Fisher, other roles in film & TV |
The pattern: the actor is significantly older than the character he portrays, and his personal life is well-documented while the character’s inner world remains open to interpretation.
Is Jeremiah Fisher LGBTQ?
This is one of the most frequent questions about the character. The The Summer I Turned Pretty Wiki (fan wiki) describes Jeremiah as “popular, bisexual, athletic, playful, easygoing, and the life of the party.” Similarly, Cosmopolitan calls him “the ultra-flirty younger Fisher brother.”
Character sexuality in The Summer I Turned Pretty
- In the books by Jenny Han, Jeremiah’s sexual orientation is not explicitly labeled, but he has romantic relationships with both Belly and other characters.
- Some fans and online communities interpret him as bisexual based on his behavior and dialogue.
- The TV series has not explicitly confirmed a LGBTQ identity for Jeremiah, leaving room for interpretation.
The implication: while the fan wiki explicitly uses the term “bisexual,” canon confirmation from the show or author remains absent. Viewers may see what they want in the character, but the official text is ambiguous.
Fan theories and author’s intent
- Author Jenny Han has not made a definitive statement about Jeremiah’s sexuality in the series.
- The fan wiki reflects community consensus, not official canon.
- Some fans argue that his flirty personality and openness suggest a bisexual identity, but this remains speculative.
The upcoming season may provide more clarity. If the series follows the books closely, Jeremiah’s romantic arc with Belly will dominate, leaving little room for explicit LGBTQ exploration.
The trade-off: fans who want representation may find the ambiguity frustrating, while the show’s focus on a love triangle keeps the story centered on Belly’s choices.
Who Is Jeremiah Fisher in Real Life?
Jeremiah Fisher is a fictional character from The Summer I Turned Pretty, but the man behind the character is very real. His name is Gavin Casalegno, an American actor born in Texas.
Real name: Gavin Casalegno
- Full name: Gavin Perry Casalegno (Wikipedia)
- He is an American actor (Wikipedia)
- According to Park Magazine NY, he is “a Texas-born actor best known for playing Jeremiah Fisher.”
Age and background
- Born on September 2, 1999, making him 25 years old in 2025 (The New York Times)
- He began acting at a young age, with early roles in film and television.
- His casting as Jeremiah Fisher was announced in July 2021 (German Wikipedia)
Appearance in the series
- The series premiered on June 17, 2022 (German Wikipedia)
- Jeremiah is 17 when the story begins (Capital FM)
- He is about a year younger than his brother Conrad (Capital FM)
Gavin Casalegno is eight years older than the character he plays, which is a common gap in teen dramas. His age adds depth to the role, but fans should remember that Jeremiah is a high schooler, not a 25-year-old.
Why this matters: the actor’s real age and life stage affect how he approaches the character, but the show’s writing keeps the focus on teenage emotions.
Is Gavin Casalegno Married?
Yes, Gavin Casalegno is married. He tied the knot with Cheyanne Casalegno in 2023. Several of his The Summer I Turned Pretty co-stars attended the wedding.
Marriage to Cheyanne Casalegno
- Married in 2023 (Capital FM)
- Cheyanne is often seen on Gavin’s social media, but keeps a relatively low profile.
- Her exact age is not publicly confirmed, but she is believed to be in her early 20s.
Ex-girlfriend
- Gavin has been in at least one public relationship prior to his marriage, but details are private.
- No confirmed information about an ex-girlfriend is available from reliable sources.
TSITP cast at wedding
- Co-stars including Lola Tung (Belly) and others attended the ceremony (Capital FM)
- The wedding was a private event, but photos circulated on social media.
Friendship with Lola Tung
- Gavin and Lola Tung are close friends off-screen (Capital FM)
- Their chemistry on screen is often praised, but it’s purely platonic in real life.
Gavin’s marriage means he is off the market, but fans often ship his character with Belly. The actor’s real-life relationship does not affect the fictional love triangle.
The pattern: The actor’s personal life is stable and supportive, which may help him deliver a convincing performance as a teenager navigating first love.
How Tall Is Gavin Casalegno?
Gavin Casalegno’s height is a topic of frequent curiosity. According to Capital FM, he is listed at 6 feet tall. IMDb gives a slightly different figure of 6′ 2″ (1.88 m).
Height and physical appearance
- Most sources agree on approximately 6 ft 0 in.
- He has brown hair and blue eyes.
- His natural tan complexion is often noted by fans.
Tan and Italian heritage

Religious beliefs
- Gavin Casalegno’s religious views are not publicly disclosed.
- No reliable source confirms any specific faith.
Height and appearance are often discussed in fan communities, but they have no bearing on the actor’s talent or the character’s depth. The discrepancy between sources (6’0 vs 6’2) is common for celebrity heights.
The implication: fans should treat height claims with a grain of salt. The official number from Capital FM is likely the most reliable, but even that can vary.
How Old Is Cheyanne Casalegno?
Cheyanne Casalegno, Gavin’s wife, keeps a low profile. Her exact age has not been publicly confirmed, but she is believed to be in her early 20s, similar to Gavin’s age.
Cheyanne Casalegno’s age and background

- She is believed to be around 22-24 years old (educated guess based on appearance and timeline).
- She married Gavin in 2023.
Relationship with Gavin
- The couple appears happy together on social media.
- They have been together for several years before marriage.
- Cheyanne is not involved in the entertainment industry.
Because Cheyanne values privacy, fans should respect that not all details of her life are for public consumption. The lack of information is intentional, not a conspiracy.
Why this matters: The mystery around Cheyanne’s age reflects a broader trend of celebrities’ spouses choosing to stay out of the spotlight. For fans, the takeaway is that Gavin’s personal life is his own, even if he shares some glimpses.
Confirmed Facts vs. What’s Unclear
Confirmed facts
- Gavin Casalegno’s birth date: September 2, 1999 (Wikipedia)
- His marriage to Cheyanne Casalegno in 2023 (Capital FM)
- His role as Jeremiah Fisher in The Summer I Turned Pretty (The New York Times)

What’s unclear
- Exact sexuality of Jeremiah Fisher (canon vs fan interpretation)
- Gavin Casalegno’s religious beliefs
- Details of his ex-girlfriend
- Cheyanne Casalegno’s exact age
The pattern: the verified facts are solid, but the gaps are where fan speculation thrives. The unconfirmed items are all personal or interpretive, not factual errors.
Key Perspectives
“Jeremiah is the ultra-flirty younger Fisher brother.”
— Cosmopolitan, character profile
“Jeremiah is described as popular, bisexual, athletic, playful, easygoing, and the life of the party.”
— The Summer I Turned Pretty Wiki, fan wiki
“Gavin Casalegno, 25, is the actor who plays Jeremiah Fisher.”
— The New York Times, August 2025 article
The catch: the fan wiki uses “bisexual” as a descriptor, but without official confirmation from the show, it remains a fan interpretation. The New York Times confirms the actor’s age and role, giving authoritative weight to the biographical details.
For fans of The Summer I Turned Pretty, the clear implication is that the character of Jeremiah Fisher will continue to be a fan favorite, while the actor’s real-life story is one of early success and stable personal life. The choice is simple: enjoy the fiction without demanding the actor’s personal life match the character’s, or dive into the speculation—but remember that the facts are thin.
