Recently, Katie announced she had to pull out of the final week of Peter Pan, where she played Tinkerbell, as she had been taken ill.
Speaking on Lorraine today (January 6 2020), Katie revealed what had happened to force her to quit the show.
Katie told host Lorraine Kelly: “Basically I was feeling a bit under the weather, but I just powered through, didn’t think about it.
“I just thought ‘right I have a cold’ and we were doing three shows a day at one point.
“I loved every second of it but I was feeling a bit off and sick and hot and a bit stumbly and I thought ‘this is really weird’. I just felt really spaced out.
“And then in between shows I fainted and then all of it is a bit of a blur. It was very dramatic.
“There was an ambulance, I don’t remember that, I just remember waking up in A&E in my Tinkerbell costume.”
She continued saying: “The doctor put it down to exhaustion and being ill and I actually had this virus and because I didn’t have any rest I needed bed rest.
“So I had a couple of days bed rest and I was like ‘right I really don’t feel well still, something’s off’ so I went to my own doctor and he said ‘you’ve had this virus you need to have one to two weeks bed rest'”.
Katie asked the doctor if she could make a cameo in the show as she hated having time off, but she was told she needed to rest.
Tinkerbell is Katie’s first acting role since leaving Coronation Street.
