A new kind of mission is underway for “The Challenge” stars Olivia Kaiser and Theo Campbell—parenthood. The couple, who first met and began dating while filming “The Challenge: Battle of the Eras” in 2024, announced they are expecting their first baby together in a heartfelt post shared on July 7.
Olivia Kaiser and Theo Campbell Announce Pregnancy
“Our sweetest little secret,” they wrote in the caption of the Instagram post, alongside a photo of them holding an ultrasound in a sunlit field. “We’ve been enjoying some time off the grid—embracing the quiet, the love, and the magic of what’s to come. Now it’s time to let you in on the journey. Our little one is arriving soon.”
According to the couple, their baby is due in December 2025, and they’re already preparing for the arrival with an adorable all-white onesie. The moment marked a major milestone for both stars, especially Campbell, who is already a father to four-year-old son Aries.
He also shared a sweet message on Instagram Stories, reposting a tweet Olivia shared in December 2023 that read: “Babies are literally the biggest blessings… I can’t wait to become the best version of myself to be the best mom ever.” In response, Campbell wrote, “I remember seeing this before we met… Congrats, baby girl. You’re gonna be the best mum (mom) ever.”
Their “Challenge” castmates flooded the post with well wishes, including Michele Fitzgerald, who wrote, “OMGGG IM AN AUNTIEEEEEEEE,” and Nurys Mateo, who hilariously added, “I literally JUST said I think you’re pregnant the other day!! Intuition is wild. Congratulations you two.”
From Reality TV Romance to Real-Life Family
Fans have been following Olivia and Theo’s journey since sparks flew during season 40 of “The Challenge,” but their relationship has been blossoming off-screen too. The couple confirmed they were dating in spring 2024 and quickly became one of the franchise’s most talked-about love stories.
In April, Theo teased that things were getting serious when he posted a TikTok of Olivia trying on engagement rings, joking, “She’s moving too fast.” While playful in tone, the post only fueled speculation that an engagement might be on the horizon.
The pair’s connection was evident during their time on “The Challenge: Battle for a New Champion,” and they’ve continued to grow closer since. Speaking to InTouch Weekly, Olivia shared, “Theo and I, we just kind of hit it off. We have fun together, and it’s easy.”
She later told Us Weekly, “We get each other in a way that’s hard to find,” noting their chemistry wasn’t just for the cameras. “It’s been building steadily behind the scenes.”
Both stars will appear on “The Challenge” season 41, “Vets and New Threats” which premieres July 30 on MTV.
