A Look Back: Dylan O'Brien's Past Relationships and Rumors

Before his current relationship with Rachael Lange, Dylan O'Brien's love life was marked by one long-term, high-profile relationship and several short-lived dating rumors that have captivated fans and the media.

The Long-Term Relationship: Britt Robertson (2012–2018)

Dylan O'Brien's most significant and public relationship was with actress Britt Robertson. The two met while co-starring in the romantic comedy film The First Time (2012). Their romance began around 2012 and lasted for approximately six years, making them one of the most stable young Hollywood couples of the time. They were often photographed together at premieres and events, but they ultimately split around 2018.

Rumored Links and Short-Lived Connections

Following his split from Robertson, O'Brien was linked to several other notable figures, often based on fleeting public sightings or social media interactions. These connections were largely unconfirmed and short-lived, highlighting his preference for privacy.

  • Chloë Grace Moretz (2018): The two were rumored to have hooked up in 2018, though this was never confirmed by either party.
  • Sarah Ramos (2020): During the pandemic, O'Brien was linked to actress Sarah Ramos, mainly based on a few social media posts and collaborations.
  • Sabrina Carpenter (2022): One of the most talked-about rumors involved singer and actress Sabrina Carpenter. The pair were spotted together on a few occasions in 2022, leading to widespread speculation of a brief romance.
  • Gracie Abrams (2022): O'Brien was also rumored to have dated singer-songwriter Gracie Abrams around the same time in 2022, though this link was also based on circumstantial evidence.

The timeline of his dating history shows a clear pattern: a single, long-term public relationship followed by a period of extreme privacy and unconfirmed rumors. His decision to keep his current relationship with Rachael Lange out of the spotlight is consistent with his overall approach to fame, prioritizing his personal connection over public attention.

The Future of Dylan O'Brien's Private Life

As Dylan O'Brien continues to take on challenging and diverse acting roles, from independent films like Ponyboi to potential blockbuster projects, his private life remains a source of fascination for his dedicated fanbase. The steady, quiet nature of his relationship with Rachael Lange, evidenced by their 2025 public outings and shared moments, suggests a mature and grounded partnership.

While the actor himself rarely speaks about his girlfriends, his actions—such as attending the Sundance Film Festival with Lange—speak volumes. For now, it is clear that the actor is happy, focused on his career, and sharing his life with a woman who appreciates privacy as much as he does.
