Love Island star Olivia Kaiser has revealed she was secretly pregnant while filming The Challenge.

The 33-year-old, who first shot to fame on Love Island USA before becoming a fan favourite on MTV’s hit competition show, stunned fans after admitting she had no clue she was expecting at the time of filming.

During an Instagram Q&A, one follower asked: “Looking back, did you have any pregnancy symptoms while filming?”

Olivia, from Anchorage, Alaska, replied:

“I didn’t! I was soooooo tired and I think threw up once. But I thought that was because of stress from the game.”

The reality star revealed in July that she and boyfriend Theo Campbell – who first rose to fame on Love Island UK – are set to welcome their first child together later this year, as reported by Need To Know.

The couple confirmed the news with a glamorous lakeside photoshoot, revealing the baby is due in December.

Theo, 33, went on to appear on season 40 of The Challenge, where he later met Olivia.

Now it’s emerged she was already carrying their little one while filming the gruelling season 41 – which has just hit screens.

Olivia, who previously won season 3 of Love Island USA with Korey Gandy, managed to throw herself into the brutal physical and mental tasks of MTV’s longest-running reality competition show without even realising she was pregnant.

The programme pits stars from Love Island, Big Brother and Survivor against each other in high-stakes challenges for a massive cash prize.

Fans were quick to connect the dots after her baby announcement – amazed she had managed to compete while already in the early stages of pregnancy.
