Megan Barton Hanson was rushed to hospital this morning (10.04.19) after suffering an allergic reaction.
The former "Love Island" star - who recently split from Wes Nelson - fell ill during the night so headed to a medical facility to be treated for the mystery ailment.
A source told MailOnline: "Megan was rushed to hospital this morning with an allergic reaction.
"Doctors are still trying to establish what has caused it and she is currently undergoing tests to determine this.
"Megan went into hospital in the early hours after suffering pain and discomfort throughout the night."
In February, Megan revealed she was undergoing therapy following her split from Wes.
She said: "I need to make sure I'm in a good place. I've gone back to therapy. I'm doing (cognitive behavioural) CBT therapy, that's a way they teach you to rationalised your thoughts and keep going over things."
In January, Megan was rushed to hospital after she was struck down with a bladder infection leading to a "nightmare few days" when the problem spread to her kidneys.
She wrote: "Glad to be home after a nightmare few days! Don't ignore a bladder infection it WILL spread to your kidneys.
"Never been in so ill in my life!! (sic)"
The 25-year-old star also praised her parents for writing her a lovely get well soon note and sending her some flowers.
She wrote: "My parents are the best nothing worse than being away from your family when your poorly thank you (sic)"
