Another couple from MTV’s “The Challenge” is expanding their team! Olivia Kaiser and Theo Campbell, fan favorites from “Battle of the Eras,” shared that they’re expecting their first child together. The couple, who first confirmed their relationship in June 2024, announced the pregnancy in a heartfelt Instagram post earlier this month. A few days later, they shared a clip on Reels and gave their fans a peek at their gender reveal party.
‘The Challenge’ Stars Went From Reality TV to Real-Life Love
Kaiser and Campbell have a love story that spans across two versions of “Love Island.” She won “Love Island USA” season 3, while he competed on “Love Island UK” and later became a staple on “The Challenge.”
Though their paths didn’t cross on the dating shows, fate clearly had other plans. The two met off-screen and competed together on “Battle of the Eras,” then went public with their romance in mid-2024. Now, just a year into their relationship, the couple is taking on a whole new kind of challenge — parenthood.
Theo Campbell and Olivia Kaiser’s New Baby is Due in December
In a dreamy Instagram photo shoot by Alexa Hudson, Kaiser and Campbell posed by a lakeside in coordinating white outfits while holding an ultrasound and a baby onesie that read “coming soon.”
“Our sweetest little secret. 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,” Kaiser, 33, wrote in the caption.
The post also included a piece of decor hinting at the due date. It read, “Our little adventure begins Dec. 2025.” Kaiser later confirmed her actual due date is December 5th, saying that she’s just “shy of five months pregnant.”
It’s a Boy! For ‘The Challenge’ Stars
Shortly after the announcement, the couple dropped a sweet gender reveal video on Instagram Reels, confirming that they’re having a baby boy. While this will be Kaiser’s first child, Campbell, 33, is already a proud dad. He became a father in 2021 when he welcomed his son, Aries, with influencer Sapphire Yhnell.
When it came time to share Kaiser’s baby news, Campbell added a sweet touch by reposting one of her 2023 tweets. It read, “Babies are literally the biggest blessing 🥹 Working everyday to become the best version of myself to be the best mom ever.” When he reposted Kaiser’s tweet, Campbell added his own caption.
“I remember seeing this before we met. Congrats baby girl, you’re gonna be the best mum (mom) ever❤️❤️,” Campbell wrote.
“The Challenge: Battle of the Eras” is now streaming on Paramount+.
