Jessie Wynter, 26, was on holiday in the US when she was admitted with a mystery illness.
It’s not yet known why Jessie was poorly as she shared snaps from out of her hospital window.
‘Not how we thought the trip would be ending,’ wrote Jessie, alongside a picture of her hospital wristband.
Jessie has been travelling with her Love Island boyfriend Will Young, stopping off at Chicago in recent days.
They left the UK last month to visit Jessie’s family and friends in Australia before embarking on the trip.
Jessie added: ‘Also, thanks for all the messages. You guys are the sweetest.’
She reassured fans: ‘I’m okay now.’
Since leaving the Love Island villa in South Africa earlier this year Jessie and Will have shunned the usual reality star party scene for a quiet life on his farm.
But last month they left for an adventure Down Under – and haven’t stop travelling since.
Despite making the most of their freedom as a young couple, farmer Will, 23, made his feelings about Jessie, 26, very clear as he shared a snap of her sleeping on the plane, proudly writing: ‘That’s my baby muma.’
Since appearing on the show over winter, Will has dropped numerous hints that he thinks Jessie is ‘marriage material’ and that he plans to propose to her.
And it’s not the first time he’s raised eyebrows about babies, he previously posted a snap of Jessie on his Instagram story, showing her in a supermarket posing down the baby aisle and surrounded by nappies.
