Somewhere between a political science lecture hall and a smartphone camera propped against a dorm room mirror, a future Hollywood leading man was quietly being built. Nobody handed Jack Martin a script for this one, yet the internet decided he deserved a starring role anyway. What started as pandemic boredom eventually turned into red carpets, network television, and a very public romance with Lili Reinhart that keeps people typing his name into search bars.

As his television resume kept quietly stacking up, one detail always followed close behind: the woman standing next to him at premieres.

Jack Martin, born John Martin, arrived in Columbia, Maryland, and grew up in McLean, Virginia, long before anyone recognized his face from a television screen. He enrolled at Georgetown University to study political science, graduating a year early in December 2019 with entirely different career plans forming in his head. Acting had already pulled him in during a single college semester, and there was no turning back after that.

Formal training followed at USC's School of Cinematic Arts and NYU's Tisch School of the Arts, sharpening instincts that TikTok had already started rewarding. Comedy sketches poking fun at preppy culture and corporate life turned Martin into a recognizable face online, racking up hundreds of millions of views. That online following eventually caught the attention of agents, setting up the next chapter of his career.

While the internet fame opened doors, network television is where Martin truly cemented his name.

Jack Martin's television and film roles expanded rapidly after his TikTok breakout

Jack Martin landed a series regular role as Josh Harris on the NBC sci-fi drama La Brea, holding the part across three seasons between 2021 and 2024. He later stepped into Mindy Kaling's world, playing aspiring producer Josh Teitelbaum in the Hulu comedy Not Suitable for Work, a series that premiered in 2026 before getting canceled after a single season. Guest appearances on The Rookie and All Rise rounded out his growing television footprint.

Film work arrived alongside the television roles, including Senior Prank and the Hulu comedy Pizza Movie, both released in 2025 and 2026 respectively. Every credit added another layer to a career that started with nothing more than a phone camera and a punchline. Somewhere along this rapid rise, Martin's personal life started generating just as much attention as his acting resume.

As his career picked up speed, so did a romance nobody saw coming from a Riverdale joke.

Jack Martin and Lili Reinhart's relationship began after a TikTok video caught her attention

The origin story practically writes itself: Jack Martin posted a TikTok poking fun at Riverdale, and Lili Reinhart, the show's own star, slid into his direct messages soon after. Photographs of the pair kissing outside LAX surfaced in April 2023, giving the public its first real glimpse of the budding connection. Instagram made things official in July of that same year, with Martin posting the confirmation himself.

Their red carpet debut arrived months later at the Venice Film Festival in September 2023, marking the moment the relationship stepped fully into public view. Comparisons to Reinhart's previous relationship with Riverdale co-star Cole Sprouse followed almost instantly, though the couple kept their approach noticeably different. Privacy became their preferred method of handling public curiosity from that point forward.

While outside comparisons kept surfacing, the couple's own words about each other told a very different story.

Jack Martin and Lili Reinhart continue supporting each other through

Lili Reinhart has openly credited Jack Martin's steady support during her chronic health struggles, describing their bond as one of the most meaningful periods of her personal life. Martin has returned that sentiment consistently, calling her one of the kindest people he has encountered and expressing daily gratitude for her presence. Their dynamic reads less like typical celebrity romance coverage and more like genuine partnership built away from constant public scrutiny.
