The Unexpected Relationship Timeline: From Rivals to Parents
The relationship between Theo Campbell and Olivia Kaiser is a testament to the unpredictable nature of reality TV. They met while filming *The Challenge* Season 40: *Battle of the Eras* in early 2024, a season that pitted reality stars from different franchises against each other. What started as a casual on-set connection quickly escalated into a deep, committed bond that continued long after the cameras stopped rolling.
The Challenge Spark (Early 2024)
Olivia and Theo first connected during the filming of *The Challenge* Season 40. Despite being formidable competitors known for their strategic gameplay, a romantic chemistry developed between the two. This period marked the beginning of their long-distance relationship, as Theo is based in the UK and Olivia in the US.
Going Public (June 2024)
The couple officially confirmed they were dating in June 2024, sharing sweet posts on social media that delighted fans of both *Love Island* and *The Challenge*. Olivia gushed about Theo, noting that he "not only accepts but encourages me to be 100% myself."
The Pregnancy Announcement (July 2025)
In a massive July 2025 announcement, Theo and Olivia revealed they were expecting their first child together. The news came as a complete shock to many, as they had kept the pregnancy relatively private while continuing to compete on Season 41 of *The Challenge*. The couple later shared that Olivia learned she was pregnant shortly after completing a final, making her approximately seven weeks pregnant during the intense competition of *The Challenge: Vets & New Threats*.
Atlas Kaiser Campbell: The Newest Challenge Baby
The most recent and definitive proof that Theo and Olivia are still together came with the birth of their son. The couple welcomed their baby boy, Atlas Kaiser Campbell, on November 20, 2025. Atlas was born two weeks earlier than expected, weighing in at 5 lbs. 5 oz. The announcement was made during the finale week of *The Challenge* Season 41, creating a heartwarming moment for the reality TV community.
The Blended Family Dynamic
Atlas is Olivia’s first child, but Theo’s second. He is already a father to a son named Aries, whom he welcomed in 2021. This new chapter sees Theo and Olivia navigating the complexities of a blended family, all while maintaining their long-distance relationship across continents. Fans are keen to see how the new family dynamic plays out, especially with both parents being active in the demanding world of reality television.
Topical Authority: Clearing Up the Other 'Theo and Olivia' Drama
For those familiar with the reality TV landscape, the question "Are Theo and Olivia still together?" often refers to a different, older relationship. For the sake of topical authority and clarity, it is important to distinguish the current couple (Kaiser and Campbell) from a previous pairing.
The Olivia Attwood Connection
Theo Campbell had a brief, highly publicized romance with fellow *Love Island UK* contestant Olivia Attwood. This relationship, however, ended years ago. Olivia Attwood has since moved on and is now married to footballer Bradley Dack, while Theo has found lasting love with Olivia Kaiser. The history between Theo and Olivia Attwood is ancient news in the reality TV timeline and has no bearing on the current, happy status of Theo Campbell and Olivia Kaiser.
What’s Next for Theo and Olivia?
With the birth of Atlas Kaiser Campbell, the focus for the couple has shifted to parenthood. Their commitment to each other, despite the challenges of distance and their demanding careers, has been a source of inspiration for their followers. While they continue to support each other’s careers, including any future appearances on *The Challenge* or other reality shows, their immediate future will be centered on raising their son.
The fact that they competed against each other in the final stages of *The Challenge* Season 41 while expecting a baby is a testament to their competitive spirit and their unique bond. Their story—from a hookup on a competitive reality show to a committed partnership and welcoming a child in 2025—confirms that they are not only still together but are building a strong, lasting family unit. The question "Are Theo and Olivia still together?" is definitively answered with a resounding yes, and a new baby to show for it.
