Lili Reinhart and Boyfriend Jack Martin’s Relationship Timeline

Lili Reinhart and Jack Martin seem to be living their best life after taking things public.

The pair first sparked romance rumors in April 2023 when Reinhart was spotted kissing Martin outside of Los Angeles International Airport, according to photos published by Page Six at the time.

One month prior, Reinhart’s ex and former Riverdale costar Cole Sprouse was a guest on the “Call Her Daddy” podcast where he smoked a cigarette for most of the appearance. Martin subsequently mocked Sprouse in a parody video where he had two cigarettes in his mouth and a third behind his ear while pretending to be the “third Sprouse brother” who was “finally speaking out.”

Fans were quick to point out the similarities between Reinhart’s current and past beau — even referring to Martin as Sprouse’s lookalike.

Reinhart and Sprouse dated on and off from 2017 to 2020. She addressed their breakup for the first time in August of that same year.

“[The split was like a] black tunnel [that] was never going to end,” Reinhart recalled to Elle at the time. “I couldn’t see the light. I was like, ‘I feel like I’m dying.’ … I’ve seen a lot of people when it comes to heartache and grief and breakups, and they try to get that void filled with sex, with coke, with food, with drinking, [but] the void is still there. I took the road less traveled and just dealt with my s—t. I had to face my own pain head-on.”

Following her and Sprouse’s split, Reinhart waited to go Instagram official with Martin until August 2023 calling the comedian “my cowboy” and sharing pictures of them together for his birthday.

“I’m so grateful for the light you’ve brought into my life,” Reinhart gushed via Instagram Stories at the time.
