Lili Reinhart has roped herself a keeper.
After all, the Riverdale star shared a photo of Jack Martin in his best Western attire in honor of his 25th birthday. Alongside a picture of the La Brea actor in a black Stetson and matching tank top, Lili wrote on her Instagram Story Aug. 3, "It's my cowboy's birthday."
She also shared a snapshot of Jack snacking on some pastries, writing in the caption of another post, "I'll split my pain au chocolat with you any day."
The 26-year-old ended her tribute with a sweet snapshot of herself—clad in a black dress paired with a coordinating headband and pair of knee-high boots—tightly hugging Jack as they stood on a dock by the ocean. "I'm so grateful for the light you've brought into my life," Lili wrote. "Happy birthday, mon petite."
In response, Jack re-shared Lili's post on his own Instagram Stories, adding along with two heart emojis, "So grateful for you."
Lili was first linked to Martin in April, when the pair were spotted sharing a goodbye kiss before her flight at the Los Angeles International Airport.
News of the romance came one year after a source told E! News that Lili and Ozark actor Spencer Neville had been "casually seeing each other" after meeting through friends in the industry. At the time, the insider shared that Spencer, 32, was "the first person since her breakup" with Riverdale costar Cole Sprouse that "she's been really into."
And Cole has been very candid about just how tough it was to get over his 2020 split with Lili, who he dated off-and-on for three years. As he explained on Call Her Daddy in March, "It was really hard for both of us and that's okay."
"I think the work thing got difficult because it was hard to suspend all the way we felt about each other and it didn't afford us the luxury of distance to really overcome that," the 30-year-old continued. "I know we both did quite a quite a bit of damage to each other."
However, the Suite Life of Zack & Cody alum noted that the exes have since moved past their heartbreak. "We're good friends now, which is awesome," said Cole, who has been dating Ari Fournier since 2021. "We work really well together now."
