All About Dylan O’Brien’s Girlfriend, Rachael Lange

Actor Dylan O’Brien is best known for his roles on MTV’s Teen Wolf and in The Maze Runner, with a cemented status as a Hollywood heartthrob. Offscreen, he’s been seeing model Rachael Lange for the last two years, but they share very little about their relationship in public. Proof of their relationship primarily exists on Lange’s Instagram feed.

Here’s everything to know about Rachael Lange and her relationship with Dylan O’Brien so far.

Rachael Lange lives and works in New York City, and has worked as as a model with Elite New York. She now has a career as a photographer and herbalist. On her photography website, she writes about discovering photography as an art form:

My journey with film photography began in 2017 when I was modeling. Being photographed on film hundreds of times, I was captivated by its timeless, nostalgic quality—something digital could never quite replicate. I started keeping a film photo diary, shooting on disposable cameras, and over the years, that small habit evolved into a deeper artistic pursuit.

Lange shared photos of O’Brien picking flowers on her photography Instagram in April 2025 post, writing, “Lover in the tulip fields.”

The pictures look like they could have been taken in Amsterdam—and O’Brien and Lange certainly travel a lot as a couple. They visited Japan in July 2024:

Then went to Thailand in April 2025:

Lange is very interested in nutrition and herbal medicine, and frequently shares her recipes online:

As well as footage from harvest and preparing herbs:

In January 2023, the pair was seen holding hands at Paris Fashion Week, Entertainment Tonight reported at the time. O’Brien made his first appearance on her Instagram in October 2023, in a carousel captioned, “Really cute fall things.”

It included a photo of O’Brien pulling a cart with their pumpkins and smiling over his shoulder at her. He appeared in another video she shared in December, kissing her cheek by the Christmas tree.

They have not made any appearances at official events or red carpets, but they were photographed at the Sundance Film Festival in January 2025.

They were most recently seen in New York City in May 2025. Instagram gossip page DeuxMoi shared photos of them walking their dog before stopping for a passionate kiss in the park.

On May 18, O’Brien made another appearance on Lange’s Instagram page, kissing her on the cheek as she smiles.
