“I met ‘the man’ on TikTok. Yeah, I did,” Lili said on The Drew Barrymore Show in 2025.

She continued, “He made a video making fun of Riverdale, in jest. So we ended up following each other and then and then one day just sort of, I mean, I DM’d him… I usually, in my twenties, I was the one making the moves.”

“We, we went on our first date and it lasted a whole weekend. It did,” Lili added. “It was a very quick, I love you, not that weekend that would have been a little bit much, but it, but it happened very quickly. I feel like he kind of instantly became my best friend and still is to this day. I feel like they say you should be with your best friend and I’m absolutely with my best friend.”

Lili Reinhart has opened up about making their relationship work while being away from each other

With both of them having busy acting careers, they’re often away from each other for long periods of time.

“I’m in my lover girl era right now,” Lili told Marie Claire. “It’s deeply hard on me to be apart from the person I love. I’m a very domestic woman, and I love to be at home and sit on my couch with my person and my dog; there’s nothing that brings me greater joy than that specifically, and when I can’t do that, my mental health suffers.”

She added, “When I’m working, he visits me; when he’s working, I visit him; and if we’re both working at the same time, which happened a lot this year, we just have to put our heads down and get through it. The feeling of missing someone prolonged over eight weeks is exhausting.”
