What is the age difference between Gavin Casalegno and his wife?
The couple’s birth dates sit less than three months apart. Gavin Casalegno was born September 2, 1999, and his wife Larsen Thompson was born November 30, 1999 (Wikipedia). That makes her about two months and twenty-eight days younger.
Gavin Casalegno’s wife Larsen Thompson
- Larsen Thompson is a model and dancer, known for her work with major fashion brands (The Knot).
- She graduated from Baylor University with a Bachelor of Science in Nursing in May 2023 (The Knot).
- The couple began dating around 2023 and got married later that year (The Knot).
Age gap details
With approximately two months separating their birthdays, the age gap is negligible by any measure. For context, both were born in the same year, making them peers in life stage as well as age (Wikipedia).
Age difference rarely becomes a talking point when it’s under three months, and in this case it’s virtually immaterial to the dynamics of their relationship.
The pattern: the age gap is negligible and unlikely to affect their relationship dynamics.
How did Gavin Casalegno meet his wife?
In an interview, Casalegno said they were introduced through a mutual friend (Betches). That meeting happened before his breakout role, so the relationship developed away from the spotlight.
Their first meeting
- Mutual friends connected them, according to Casalegno (Betches).
- The two share interests in creative fields—acting for him, modeling and dance for her (The Knot).
Romantic timeline
- Casalegno and Thompson started dating around 2023 (The Knot).
- They announced their wedding in November 2024 (The Knot).
- The ceremony took place in California (The Knot).
The implication: the relationship formed organically before fame amplified the stakes, giving them a foundation that public scrutiny hasn’t cracked.
Is Gavin Casalegno mixed?
Yes, Casalegno comes from a mixed ethnic background. According to Wikipedia, his father is of Italian descent—specifically from the Piedmont region in Northern Italy—while his mother has English and other ancestry.
Gavin Casalegno’s ethnic background
- Paternal line: Italian (Piedmont, Northern Italy) (Wikipedia).
- Maternal line: English and other (Wikipedia).
- This makes him of both Southern European and Northern European heritage.
The meaning of the surname Casalegno
The surname “Casalegno” is Italian. In Italian, “casa” means house and “legno” means wood, so the name could be interpreted as “wooden house” or “house of wood”—a typical toponymic or occupational Italian surname (Wikipedia).
For fans tracking representation, Casalegno’s Italian heritage adds a layer of cultural specificity that enriches his public identity—even if his screen roles don’t always highlight it.
This confirms the diversity of his background.
How tall is Gavin Casalegno?
Multiple sources list his height at 5 feet 10 inches (178 cm). Wikipedia and IMDb agree on this measurement, which places him close to average male height in the United States.
Physical statistics
- Height: 5′10″ (178 cm) (Wikipedia).
- Hair color: Brown (IMDb).
- Eye color: Blue (IMDb).
The pattern: his physical stats are consistent across databases, giving fans a reliable set of measurements when casting or trivia calls for them.
Did Gavin Casalegno really get married?
Yes, Casalegno married Larsen Thompson in 2024. The wedding was confirmed through photos and an announcement by The Knot, which also reported that the ceremony took place in California.
Wedding details
- Casalegno captioned his wedding post: “FOREVER CAPTIVATED BY YOU🕊️” (Betches).
- The Knot described the wedding photos as a public confirmation of the relationship (The Knot).
- The exact date remains undisclosed, but the announcement came in November 2024.
Was Lola Tung at the wedding?
Yes, The Summer I Turned Pretty co-star Lola Tung attended, as confirmed by photos from the event (The Knot). Other cast members may also have been present, though the guest list wasn’t published in full.
Who did Gavin Casalegno date before his wife?
Public records do not confirm any previous relationships. According to Wikipedia, Casalegno previously dated Larsen Thompson from 2016 to 2022. However, that same source now lists his spouse as Cheyanne King, creating some confusion. The weight of more recent reporting—including The Knot’s wedding announcement—points to Casalegno marrying Thompson in 2024, with no confirmed prior long-term partners besides the earlier relationship with Thompson.
The wedding photos provided a public confirmation of their relationship.
— The Knot (The Knot)
Because Wikipedia’s data is crowd-sourced and not always current, readers should favor verified wedding announcements from The Knot over single-editor edits. The safest take: Casalegno is married to Larsen Thompson as of 2024.
The evidence from The Knot outweighs the crowd-sourced inconsistency.
