Dylan O’Brien and Rachael Lange’s Relationship Timeline Is Extremely Low-Key (and Still Very Cute)

If you’re in the group of girls/gays/theys that had a massive crush on Dylan O’Brien growing up, thanks to his roles on Teen Wolf and The Maze Runner, you’re not alone. But…we’re going to hold your hand when we say this: Dylan is officially off the market, and he has been for a minute now.

You might be like, “What? How? Who’s his girlfriend?” after taking that bit of information in, but I’m here to tell you that he’s been romantically linked to model Rachael Lange for a little more than three years now. Spoiler alert: they’re really cute, seem to love traveling together, and are still going strong!

They have yet to make their red carpet debut as a couple since they’re pretty private, but you’re in luck because you get to scroll through their entire relationship timeline below. You’re welcome (or, I’m sorry, if you were already thinking up a pickup line to slide into his DMs)!

Dylan and Rachael first sparked dating rumors when they were spotted holding hands at Alexandre Mattiussi’s Menswear Fall/Winter 2023–2024 show during Paris Fashion Week.

Despite arriving at the coveted event with Rachael, Dylan proceeded to hit the red carpet solo.

It wasn’t until October that Rachael hard-launched the Teen Wolf alum on her Instagram feed. She snuck not one, but two pics of Dylan in an autumn-themed photo dump, where he’s seen twirling her around and picking gourds from a pumpkin patch. Cute-cute-cute.

By the holidays, these two were in full force. Dylan made an appearance in another one of Rachael’s photo dumps as he kissed her cheek in front of a Christmas tree.

In another slide, she showed the inside of a dollhouse, which featured cutouts of her and Dylan. Honestly, this is super sweet!!

Dylan and Rachael took a romantic trip to Japan, per an Instagram post.

The couple took another trip to Thailand, where they visited historic temples and fed bananas to elephants. It was all chronicled across two photo dumps—one posted on April 3 and another on April 5—on Rachael’s Instagram profile.

Rachael also dropped another rare pic of Dylan from her film Instagram account, where he’s seen picking tulips.

DeuxMoi published photos of the couple sharing some smooches while walking their dog in New York.

2025 seemed to be the pair’s year for jet-setting, as Rachael posted another pic of Dylan—this time, from a trip to Switzerland.

The couple has yet to hit a red carpet together, but they were photographed inside the 2026 Film Independent Spirit Awards at the Hollywood Palladium on February 15.

Per Rachael’s photo dump from Sin City, Dylan seemingly crashed her girls’ trip to Vegas and hit the slots!

According to pics published by JustJared, Dylan and Rachael were spotted on a casual stroll through New York City in cozy clothes.

Rachael also shared some cute pics with Dylan from a wedding they attended in Ireland, and, of course, the couple cleans up quite nicely!

Dylan even assumed his position as Instagram Boyfriend, lol:

Aaaand that’s all on these two for now, but we’ll be back with more updates as their relationship becomes increasingly public.
