Is Miles Heizer in a relationship?

Current relationship status

Miles Heizer has been in a public relationship with Canadian actor Connor Jessup since 2018. The couple confirmed their relationship through social media and have been seen together at industry events. Neither Heizer nor Jessup has indicated any change in status. Famous Birthdays celebrity database lists Jessup as Heizer’s current partner, and no credible counter-evidence has emerged.

Previous relationships

Before Jessup, Heizer was reported to have dated 13 Reasons Why co-star Brandon Flynn around 2017. Neither actor has publicly confirmed the timeline or nature of that relationship. According to multiple entertainment outlets, the two met on the set of the Netflix series and were believed to have had a brief romance.

Public appearances

Heizer and Jessup have been photographed together at red-carpet events and casual outings in Los Angeles. Their last known public sighting together was at a film festival in 2024. No credible source has reported a split.

The implication: The relationship appears stable, but like many private couples, they keep most details offline.

Did Miles Heizer date Brandon Flynn?

Their connection on 13 Reasons Why

Miles Heizer and Brandon Flynn played friends Alex Standall and Justin Foley, respectively, on Netflix’s 13 Reasons Why. Off-screen, rumors of a relationship swirled after they were seen together frequently during the show’s first two seasons. Famous Birthdays celebrity database and several fan outlets reported the pairing, though no official confirmation came from either actor.

Off-screen romance

By 2018, both Heizer and Flynn had moved on publicly — Heizer with Jessup, Flynn with other partners. The relationship is widely believed to have been a short-term, private affair. Neither actor has discussed it in interviews.

What this means: The Flynn-Heizer relationship remains one of the most unanswered questions from the 13 Reasons Why era, but it’s almost certainly a closed chapter.

How tall is Miles Heizer?

Height in feet and meters

Most authoritative sources list Heizer’s height as 5 feet 9 inches (1.75 m). However, IMDb lists 5′ 9¾″ (1.77 m), a half-inch difference that creates a minor discrepancy. The majority of profile pages — including Rotten Tomatoes review aggregator and general bios — round to 5 ft 9 in.

Comparison to co-stars

Heizer is average height for a male actor. In 13 Reasons Why, he stood slightly shorter than Brandon Flynn (who is 6 ft 1 in) and roughly equal height with Dylan Minnette (5 ft 9 in).

The pattern: Whether 5 ft 9 in or 5 ft 9¾ in, the difference is negligible for practical purposes. The variation is typical for celebrity profiles.

How old is Miles Heizer?

Birth date and age

Miles Dominic Heizer was born on May 16, 1994, in Greenville, Kentucky. As of 2026, he is 32 years old. His birth date is consistently reported across IMDb film database and Rotten Tomatoes review aggregator.

Early life

Heizer moved with his family to Los Angeles at age ten to support his acting career. His mother worked as a nurse, and he has an older sister named Moriah (IMDb film database). He landed his first role at age 10 on CSI: Miami and his first film role in Rails & Ties (2007).

The pattern: Heizer’s career started young, grew through Parenthood, and hit a new peak with 13 Reasons Why — a trajectory that mirrors many child actors who successfully transitioned to adult roles.

The pattern for anyone tracking Miles Heizer’s career and personal life: the verified facts are solid — age, height, major roles, and his relationship with Connor Jessup. The unknowns are minor and typical for a private celebrity. For fans curious about his past with Brandon Flynn, the record is thin but the chapter appears long closed. Heizer’s latest project, Boots, marks a deliberate shift toward roles that reflect his identity, and the industry seems ready to watch.
