Lili Reinhart has been our screen queen for a minute now, which means we love following her on social media just as much as we're keen on her movies and TV shows (yes, I am still thinking of her role in Hustlers, tysm). Her collaborative TikTok account with her Riverdale co-stars-turned-IRL-besties Camila Mendes and Madelaine Petsch is truly a gem on the web, as is her personal account. Last year, the multihyphenate posted a sweet TikTok with her boyfriend, Jack Martin. "Failure at the LA County Fair. I guess I’m too old for the rides now 🥲," she wrote in the clip's caption, revealing that she and Jack got a tummy ache after hitting an upside-down ride.
Now, if you watched that clip back and thought Jack looked kind of familiar, you're not alone! Here are all the details on Lili Reinhart's boyfriend, Jack Martin so you can alert the masses your groupchat that still reminisces on the delightful chaos of Riverdale.
He's an Actor
That's right—Jack is an actor just like Lili, and he had a major role on NBC's primetime drama, La Brea, since 2021. According to his IMDb profile:
"Jack's first connection to acting came from a wild experience in fifth grade, when he fell just short of a big part in a major feature film and realized how much he loved acting."
He also had roles on CBS's All Rise and was part of a short film called In This, Our Time. Love this for him!
Jack isn't his actual name
Jack was born John Martin on August 3, 1998 in Columbia, Maryland, and grew up in McLean, Virginia, according to IMDb. That makes him a 25-year-old Leo. Cool-cool-cool.
Jack and Lili are Instagram official
Jack first posted a pic of Lili in a sweet photo dump back in July 2023 with the caption "Unbelievable, even egregious amounts of Smiling and Chilling." In September, the Hustlers actor hard launched their 'ship on her feed with another photo dump.
They made their red carpet debut at the 2023 Venice Film Festival

On September 2, 2023, the couple made things red carpet official at the Venice Film Festival in Italy when they attended Giorgio Armani's "One Night In Venice" event together.
Jack has a college degree
Per his IMDb profile, Jack graduated Georgetown University (!!!) in December 2019. He also took summer courses at the University of Southern California's School of Cinematic Arts and New York University's Tisch's School of the Arts. Not too shabby!
Plus... he's a funny dude
I'll just leave Jack's Instagram bio here as proof:
^ And, in case context is needed, Elizabeth Holmes was the founder and CEO of Theranos, which was... truly a chaotic journey from start to finish.
He also appeared on After Midnight with Taylor Tomlinson, where he cracked some jokes alongside other panelists.
He's been supporting Lili amid her diagnosis
Lili graced the February 2025 cover of Self, where she opened up about her recent interstitial cystitis diagnosis. She promoted the article on her Instagram Stories with photos from the shoot, but also gave Jack a shoutout for his support with her chronic illness.
“Also. Never in my life could I have gotten through this without my partner. It’s not easy to have a chronically ill girlfriend — when I spent months barely leaving the house, couldn’t walk due to pain, and felt incredibly depressed due to the shift in my quality of life,” she wrote alongside a pic of the actor. “Jack’s love and support has never waivered for a second during a time when my body was truly falling apart,” she added.
