The Current Flame: Dylan O'Brien's Girlfriend, Rachael Lange (2025 Update)

The biggest question for fans—"Who is Dylan O'Brien dating now?"—has a clear answer: Rachael Lange. Their relationship has moved past the rumor stage, with the two frequently referred to as a confirmed couple in recent 2025 publications.

Who is Rachael Lange?

Rachael Lange is a model and photographer known for her distinctive style and artistic work. She is not a traditional Hollywood celebrity, which aligns with O'Brien’s preference for keeping his private life away from the public eye.

  • Profession: Model and Photographer.
  • Relationship Timeline: The pair were first linked publicly around 2021, but their relationship has become more visible in 2025.
  • Public Confirmation: While neither has made a grand public announcement, photos shared by Lange on her photography Instagram in April 2025 showed O’Brien, whom she referred to as "Lover in the tulip fields," confirming their romantic involvement.
  • Recent Sightings: In May 2025, the couple was spotted holding hands and sharing a rare PDA moment during a walk in New York City, signaling the stability and seriousness of their relationship. They were also seen together at the 2025 Sundance Film Festival.

Their relationship is characterized by its low-key nature. Lange’s background in photography and O'Brien's general aversion to the celebrity gossip cycle suggest a mutual desire to maintain privacy, which likely contributes to the longevity and health of their partnership. The couple’s shared artistic interests and quiet life contrast sharply with the intense media scrutiny of O'Brien’s previous high-profile romance.

A Look Back: Dylan O'Brien's Complete Dating History and Past Relationships

Before his current connection with Rachael Lange, Dylan O'Brien had one major, long-term relationship that defined his personal life for years, along with several high-profile rumors that kept the tabloids busy. Understanding his past is key to appreciating his current, more private approach to love.

1. Britt Robertson (2011–2017): The Long-Term Romance

Dylan O'Brien's most significant and public relationship was with actress Britt Robertson. Their love story began after they met on the set of the film The First Time in 2011.

  • The Meeting: They met while co-starring in the romantic comedy, where they played high school students who fall in love. The on-screen chemistry quickly translated into a real-life relationship.
  • Duration: The couple dated for approximately six years, from 2011 to late 2017/early 2018.
  • The Breakup: The split was reported around early 2018. Given their private nature, the exact reasons for the breakup were never publicly confirmed, though long-distance and conflicting schedules due to their burgeoning careers were speculated.

This relationship was a staple of celebrity news throughout the Teen Wolf and Maze Runner eras, making their eventual separation a shock to many fans. O'Brien once spoke about how supportive Robertson was, even through his serious on-set injury while filming Maze Runner, highlighting the depth of their connection.

2. The Rumors and Short-Lived Links

Following his breakup with Robertson, O'Brien was linked to several other prominent female figures in Hollywood, though most of these connections remained firmly in the "rumor" category, often fueled by brief public sightings or social media interactions.

  • Chloë Grace Moretz (2018): The two were rumored to be dating after they were spotted together multiple times in 2018. However, neither party ever confirmed a romantic relationship, and the rumors eventually faded.
  • Sarah Ramos (2020): During the pandemic lockdown, O'Brien participated in a video series with actress Sarah Ramos, leading to brief speculation about a romantic link, which was likely just a close friendship and creative collaboration.
  • Chloe Bennet (2022): O'Brien and actress Chloe Bennet (known for Agents of S.H.I.E.L.D.) were photographed together in June 2022, sparking dating rumors. The link was short-lived and never officially confirmed.
  • Sabrina Carpenter (2022): Perhaps the most widely circulated rumor post-Robertson, O'Brien was rumored to have hooked up with singer and actress Sabrina Carpenter in 2022. This speculation was largely based on a few joint appearances, but like others, it was never substantiated as a formal relationship.

Why Dylan O'Brien's Private Life Matters to Fans

The fascination with Dylan O'Brien's personal life, particularly who he is dating, stems from his unique appeal. He achieved massive fame as a teen idol but has consistently refused to embrace the typical celebrity lifestyle. His preference for privacy makes any confirmed detail about his love life—like his current relationship with Rachael Lange—highly valued by fans who respect his boundaries but remain curious about the man behind the beloved characters.

The lack of constant updates and drama surrounding the Teen Wolf star’s relationships only adds to the interest. In a world of oversharing celebrities, O'Brien’s guarded approach to his love life, especially his enduring commitment to privacy while navigating a relationship with Rachael Lange, is a refreshing change. It suggests a focus on genuine connection over public performance, which ultimately strengthens his image as an authentic and grounded Hollywood figure. This current chapter with Lange appears to be his most stable and mature relationship since his long-term partnership with Britt Robertson, suggesting a happy and balanced personal life for the actor as he continues his successful career in 2025.
