Love Island USA’s Olivia Kaiser Expecting 1st Child With Theo Campbell

One year after confirming she found love with fellow Love Island alum Theo Campbell, Olivia Kaiser is pregnant with the pair’s first child.

The Love Island USA season 3 winner, 33, took to Instagram on Sunday, July 6, to reveal her exciting news. “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,” Kaiser wrote alongside a carousel of snaps taken during a recent maternity photo shoot. “Now it’s time to let you in on the journey… our little one is arriving soon.”

The post included 13 photos of Kaiser and Campbell, who served as a castoff during season 3 of Love Island UK, embracing their special time — and one another — in a lush field beside a tranquil lake. One shot also featured a board that revealed the child’s due date, with its text reading, “Our little adventure begins Dec 2025.” (An additional Instagram Story posted hours later confirmed that Kaiser’s due date is December 5, making her just “shy of five months pregnant.”)

The couple, both dressed in top-to-toe white ensembles, also held a print out of Kaiser’s sonogram as well as a tiny onesie with the words “Coming soon” written across the front with itty bitty foot prints.

Kaiser celebrated her news further via her Instagram Stories that night, revealing that “the love we’ve both received already is overwhelming.” Another Story promised the couple would be “uploading a YouTube video VERY soon.”

For his part, Campbell, also 33, shared his partner’s grid post via his own Instagram account that evening.

Kaiser confirmed via an Instagram Story in June 2024 that she was dating Campbell. Posting a photo of the duo feeding one another pizza while on vacation, Kaiser wrote, “He not only accepts but encourages me to be 100% myself. I’m never TOO much or not enough. I ❤️him.”

At the time, she also confirmed to fans that he had met Campbell’s family and made plans to stay connected with him despite physical distances.

In the months that followed the pair’s romance going public, Kaiser shared several special moments with her man via Instagram, including spending quality time together during the 2024 Christmas and New Year period.

In June, Campbell shared his own photos from recent outdoor outings with Kaiser, which included relaxed pool time together, hiking in proximity to stunning waterfalls and watching the sunset together in the middle of nature.
