Katie Price was forced to cancel a recent gig after coming down with a mystery illness, and it's claimed the former glamour model is worried it's something serious.
She is said to be concerned that it's coronavirus, a contagious condition that has killed 565 people worldwide.
According to The Sun, the mum-of-five has been texting her friends to ask what the symptoms are as she fears she picked it up from either her New Year's break to Thailand or a recent trip to New York.
A source told the paper: "Katie's been feeling so bad she's convinced it's more than the flu.
"She's been texting and calling friends asking what the symptoms of the coronavirus are because she's been travelling so much there's every chance she could have got it on a plane back from Thailand or Las Vegas."
Mirror Online has contacted Katie's reps for comment.
Katie had been due to appear at the LA Studio hair salon in Worth, West Sussex, for her makeup masterclass on Wednesday night.
However, she scrapped the event with just hours to go - with fans being sent an email advising them the class would not be going ahead as both Katie and her make-up artist Zoe James were not well.
Yesterday Katie recorded a video from her bed saying she was feeling ill.
She lay in bed with no makeup on and her hair down and laying unbrushed around her.
"I've been really ill and I've been bed all night and I'm staying in bed all day," Katie said.
She denied reports that she had flown to Amsterdam instead of doing the gig.
Katie added: "That person isn't me. I'm not that big and my hair's a lot longer than that... I'm actually in bed still ill."
