The mother-of-five appeared on last night's Europe: The Final Debate with Jeremy Paxman, where she admitted to being undecided and "confused" about the various issues at stake.
After listening to the panellists on the Channel 4 show, Katie said: "Well believe it or not, I came here confused, and I am more confused."
"I've never voted before, and I feel I that am pressured I have to vote this time. Lot's of my friends are in, some are out, I'm asking them lots of questions," said Katie, who added her main concern is how leaving or staying in the EU could affect son Harvey, 13.
"My son's got disabilities, so in my case, I'm thinking, what would be the best for his future? For the NHS, if he goes on holiday, and if he gets hurt there or something? There is all of this. And do I think of myself as a family? Or do I think of the country? I am just confused. This has made it more confusing!"
Katie, 38, later told Twitter users she was still confused but would definitely be casting a vote today: "Interesting evening #c4debate @Channel4News still undecided but will vote tomorrow #priceminister (sic)"
Former glamour model Katie actually stood for election way back in 2001, hoping to land the Stretford and Urmston seat. Her slogan was "For a Bigger and Betta Future." According to BBC News, her promises included free season tickets to football and tax cuts to anyone having an affair with a foreign footballer.
The polls opened at 7am on Thursday, 23 June and will stay open until 10pm, as Britain votes on whether to leave or stay within the European Union.
A slew of celebrities have come out in favour of either side. David and Victoria Beckham, Cara Delevingne and Daniel Craig are among those supporting Remain, while Vicky Pattison, Liz Hurley, Keith Chegwin and Joan Collins have voiced support for Brexit.
