Who Dated Who: the Complete Guide to Dylan O’brien’s Real Relationship History
The standard against which all of Dylan O'Brien's public relationships are measured is his multi-year partnership with actress Britt Robertson. The two met in 2011 while filming the indie romantic comedy The First Time, directed by Jon Kasdan. Their on-screen chemistry translated off-camera into a grounded, long-term relationship that began in early 2012.
Throughout their six years together, O'Brien and Robertson avoided red carpet appearances, joint interviews, and constant social media displays. They were occasionally photographed walking dogs in Los Angeles or visiting each other on film locations in Vancouver and Atlanta. When Robertson promoted projects like The Longest Ride and Tomorrowland, she offered rare, understated comments about their shared humor and mutual respect.
By late 2018, the relationship quietly ran its course. The split occurred without public statements, leaked tabloid disputes, or social media drama. Robertson eventually married entertainment figure Paul Floyd in 2023, while O'Brien continued his pattern of keeping private breakups out of public view.
