Renowned for its compelling portrayal of love across borders, “90 Day Fiancé” continues to captivate audiences by following couples as they navigate the K-1 visa process. Among the couples featured in Season 10 were Sophie Sierra and Rob Warne, whose paths crossed through social media. Originally from England but having spent much of her life in Spain, Sophie connected unexpectedly with Rob on Instagram. This digital encounter eventually led her to uproot her life and settle in California, where they married in 2023. However, by 2025, despite multiple attempts to salvage their relationship, the couple had parted ways.
Throughout their time on “90 Day Fiancé,” tensions simmered as Rob clashed with Sophie’s mother and Sophie expressed dissatisfaction with Rob’s Los Angeles apartment. Matters were further complicated when Sophie discovered Rob was still engaging with other women online, casting doubt on his commitment. Nevertheless, after addressing these issues, Sophie decided to trust Rob’s assurances of devotion, and the couple exchanged vows in an intimate Santa Barbara beach ceremony with just a handful of guests.
The challenges faced by Sophie Sierra and Rob Warne were extensively captured on “90 Day Fiancé,” and their struggles continued on “90 Day Fiancé: Happily Ever After?” Season 8, which aired in early 2024. Sophie temporarily left Rob after discovering videos from other women on his phone. Although they pursued couples therapy and sought to rekindle their connection on “90 Day Fiancé: The Last Resort,” the season concluded in December 2024 with their separation, marking what seemed to be the end of their journey together.
As of now, it appears the split is final. Rob even participated in “90 Day: Hunt for Love,” seeking new romantic prospects. In June 2025, a chance encounter at an event in Las Vegas led to speculation when videos emerged of Sophie appearing jealous of Rob’s potential new partner. In the footage, Sophie remarked that they remain legally married, sparking rumors of a possible reconciliation. However, Sophie later clarified via Instagram stories that while they maintain a cordial relationship, they are not rekindling their romance, aiming to prevent any misunderstandings among “90 Day” enthusiasts.
